I'm struggling to use GIMP as someone used to Photoshop, how can I learn GIMP properly?

Tried use GIMP a few times, but the standards feels way too different from Photoshop.

Like basically everything.

I'm not a designer, but I use such tools once in a while to make some images, and GIMP is nearly impossible to use for me.

Currently I'm sticking with Photopea on browser.
