Pretty much everything important has been said already. I’d like to add one more possible pitfall to avoid: Comparison.
Especially as a beginner you see all those great renders and artworks out there and it’s easy to loose confidence because you can’t produce anything like it yet. So as in other professions (it’s what I always tell young apprentices in my occupation) don’t compare yourself to anyone else. Take inspiration and goals from it, but don’t compare yourself. Everyone’s situation is different and people learn at a different pace, mostly due to their individual circumstances. Only compare yourself to your yesterday’s self. See improvement? Good. No improvement? Keep working on it.
It’s a toughie but you got this 🙂
