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 🎨 ✨️ don't lose yourself in too much technical skills
2) Dance
Flow, composition, animation images are like music 🎶
3) Determination
Hard to find jobs and most people give up at some point
