I envy Photoshop skilled folks. I actually have an earlier version (- 4 years old) I deactivated on my computer. I always wished I could have taken a formal class or two to learn to use it. PS was nice but for whatever reason, I was never able to master its true potential. So I returned and remained to Paintshop Pro updated which I found easier to use. Not to mention nearly equal and whole lot cheaper. But if I could master PS, I'd jump to it with glee. Meanwhile, I keep watch for one of those free online courses to offer formal courses in PS.
I taught myself using YouTube tutorials!! It’s great. Two minute lesson on how to do x, y or z.
Much better than a book
best of luck
