What do you wish you knew earlier in your Blender journey/experience

or what do you wish you didnt watse so much time on ?

I’ve been thiking what do I really want to do with Blender, and by doing this I aim to eliminate wasting my time on things I believe arent relevant

So photo realistic buildings/ineteriors and cars take my fancy (along with motion graphics).

I was wondering what things others came across at the start that they wish they knew in the beginning (first 6 months) or things they wish they hadnt spent so much time on.
