Trying to think of what I do whenever I try to make a push into a new field. I may be a bad example, but if I have the drive and really feel like I can achieve fluency in the new area I'm interested, then it ultimately isn't a problem. I've gotten to the point in my career where I feel I can learn anything as long as I have the will power to push through the initial frustration of learning.
I will make a comment about expanding your 3D knowledge though; something that seems to be a grave misconception for some people. There is no such thing as an overall best suite/tool. The best tool is the one you find that works best for you. When I was trying to break into UV texturing, I spent hours upon hours trying to figure out the art of UV unwrapping. Tried various programs that people recommended as the 'best'. What ended up allowing me to figure it out, and unwrap with ease was a tool I'd never even heard of (UVLayout). So, it really is whichever works best for you. It might take some time to find your best fit, but the search is worth it.
I'm currently working as a 3D hard surface animator right now (trying to learn organic animation atm), but I also do work in high-poly and low-poly 3D modeling, texturing, motion graphics, compositing, and environment design.
