I've done 3D and VFX for 7 years. and the only skills I've learned that really make a difference are not softwares skills but:
Painting and photography.
Hopefully you double down on them before me because I've lost a lot of time doing bad images with lots of technical skills.
The 3 D's of 3D:
1) Drawing
3d is art π¨ β¨οΈ don't lose yourself in too much technical skills
2) Dance
Flow, composition, animation images are like music πΆ
3) Determination
Hard to find jobs and most people give up at some point
