I've found that I have to go through periods of doing (hustling), and then periods of research/learning when stuck, going back to doing once unstuck. The cycle repeats itself. Transitioning between the two can be difficult. It's like switching between a "job" and being in academia. They're similar but two totally different worlds. One gives you hands-on experience, and the other book smarts. Separately neither paints a full picture, but combined they certainly do.
