And, that is a great way to “start” your journey right now. There is often, too much information to process. Adding 3D may be a bridge to far.
But… Don’t give up the possibility of 3D design as a solution in the future rather than the goal. What I mean by that is that sometimes, looking at a 3D model can help with a 2D problem. It is similar to the difference between calculus and algebra. (If you ever learned calculus, you will know what I mean.)
To give a real life example I encountered, it is discussed in this post:
All I am saying is don’t say “never” for 3D. It may become another tool in your belt that sets you apart.
