As someone who works best on paper, am I dragging my progress by working on fundamentals/etc 100% digitally (Tablet & Monitor)?

I've been doing it as a challenge, but the setup isn't as comfortable, the results aren't nearly as consistent and I'm starting to have doubts.

Am I better off building my skills traditionally until I'm confident enough to overcome the difference in medium?

(I'll add that I've been working traditionally for life, and digitally for a few years)
