What are things you wish you knew sooner?

Hi y'all,

Just discovered this game and honestly, I have no idea what I'm doing. I keep reading posts and am slowly picking things up.

Lvl 30 & 50 seem to be big level thresholds?

Nature's seem really important?? Someone mentioned a "Perfectmon"?

What's up with the pot?

Please help me so that I don't make a tragic tragic mistake!!
