I don't want to push you for the-only-good-gamestyle
But there is some things you have to understand to make your game truly enjoyable, and it's not very strict rules.
This is one of the chilliest game I know, you just doing some cozy stuff watching youtube on background.
Do not expect great fights here, combat-system here is just a clicker like in old console-games
Do not expect factory building, it's not a factory game
The strongest part is a great big worlds with TONS of riddles and loot on each step

Unique(=fun) content:

• world exploration
  
• dungeons completing
  
• side quests (not everybody know it)*
  
• new professional recipes (somebody disagree)

Grind(=boring) content:

• getting money
  
• getting ore/log
  
• farming

Our goal is to make % of grind minimal, while % of fun should be maximal
And this is possible. For me, at least.

*Talk to people in Town, they will give you quests to repair shops/lanterns/benches. It could add some interest to your activities

• You can get as many professions as you want
  
• Each new profession costs much more then previous
  
• We need luma spheres to progress in each profession*

We want to get as much money as possible doing as less work as possible.
Point is that each profession brings us way to convert resources from some type of activity into money
So what? So we need maximum professions to convert EVERYTHING we do into money.
This is the first thing you need to spend money on. Not all money, but it's much easier to play with 2-3 professions.

Some professions are connected. This is BAD option. Coz you will be forced to do same activity to get money = grind.

So:
Acheology - don't take it at start. Hardest to progress => harder to get more profit
Blacksmith and Jewerly Crafter - both requires you to loot mines. First for metals, second for crystals (always further in mines).
Treasure Hunter - praise you for opening chests + requires a bit of easy fishing (easier than for Fisherman)
Fisherman - require to do especially fishing, which can be alsmost ignored if you don't like the mechanic, but it pushes you to find new lakes in the world for new fish types
Brewer and Cooker - require you to work on farm, sometimes to get berries from other worlds. Doesn't praise you for exploring world, BUT semi-autonomous coz you don't need to work while plants are growing

you 100% need farm and Brewer or Cooker for profit + add something depends on what you prefer - Treasure Hunter/Fisherman for world exploration or Blacksmith/Jewerly Crafter if you like exploring mines (it has chests and secret doors on corners).
Acheology will be OK only if you OK with a bit of mining + a lot of tryharding dungeons to complete them without deaths

One of the most stopping thing is a require of Luma sphere to open new profession recipe.
This way you need to make new lumas as fast as you can and put a feeding pan with luma food for them to allow you going out of farm for few days
But when you collect spheres, do not forget to pet each Luma, which will gives you +1 spheres each, so x2 income
You will get new lumas after completing each of the dungeons. Even if you dies there, just run up to the end
Also, if you collect all the loot in the world, you will get a lot of coins for mushroom-man. Just buy Power Luma Food there, it will bring you +1 sphere for each, great way to get it fast
You can sleep to skip time. Lumas eat food => create spheres once per day
But it also speed up some things. Like, most of the professional crafts auto-completes after sleep, but not after day change, especially long-time brewing. Even if you went to bed at 7:55

So finally, depends on your playstyle, you will max single profession with a bit of additional profits from side-staff, or you can do all kinds of non-grind activities and receive ~average money from all of that

The other problem of the game is huge amounts of required resources for some cool things.

First of all - you need to get a single piece of wood/ore to open it in the store. So read article about money making. Now you're able to convert resource grinding into money grinding, which is much easier.

• There are 4 tiers of resources/tools
  
• To get minimal (=fastest / 1-2 repeats) animations, your tools have to be 1 more tier than resource tier
  
• Upgraded tools give luck and it really works
  
• You can buy resources in Town store

1) Max your tools (Pickaxe -> Axe -> Whip -> Hoe/Fishing rod) as fast as you can
2) Do unavoidable grind especially to open next world, do not forget to spend money to get some things faster. Put farm upgrades, new blueprints, new professions into less priority
3) Open new world - find 1x ore and 1x log
4) Run to Town store, buy that ore and max your tools
5) Go farming previous world, getting all you want, upgrading farm and all the other fun staff, now it's easy and fun

Do not forget that basic buildings are almost free, so don't be bothered building few sawmills, etc. to parallel crafting. Higher tier resources requires much more time.

Farming is a fun thing for me personal, but as it's nearly must-have to get money, I would mention how to make your farm as simple as possible

• Rabbits eat weeds from plants
  
• Chickens eat bugs from plants
  
• Sprinkler auto-watering plants and also auto-applying fertilizer
  
• Pigs producing all tiers of fertilizer if has feeding pan + plowed land
  
• Watering hose is quite cheap but MUCH more useful than watering can
  
• Upgraded hoe gives x2 resources sometimes which leads to +10-25% income on long distance
  
• Upgraded hoe can harvest multiple crops by long-pressing button
  
• Some plants require bees

So, first of all, get Watering hose and forget about clicking each cell to watering plants
Then rush to get chickens and rabbits and put it in farm area to forget about other growing problems (except fertilizer)

Later, on average profit, buy pigs and put them into any place on the island. Now you can forget about grinding resources to make fertilizer

And ofc. later build your farm around sprinklers + beehives (for high-tier plants)

So as a result, all activity on the farm will be to come there, long-press single button, collext 3x3/3x4 or even more crops at once, do it for all the area, and start crafting profession staff


My example of farm, here is two modular blocks (9x9) separated by vertical gravel path

Currently, I am going away from farm to collect chests, find books and completing dungeons, each day I come back to farm, quickly collect Luma spheres, crops and brewed drinks, put on craft next drinks, crafting few treasures/jewelry/armor from stuff from world exploration, and running back to explore the world


Ask question if I miss something
And yes, I agree that this game is not for everyone, I just look at some content as "chill and easy" while other people find it as "grind", however, hope this guide help to someone.
Have fun
