I can't upvote this enough. Burnout is real and it is horrible to experience, and could possibly derail your career for years. I was fortunate when I experienced burnout in my mid 20's that it didn't derail my career trajectory, but I have seen cases where it has.

This is definitely the #1 thing to focus on as a junior dev. Start to understand your limits. Listen to your body, become conscientious of your emotional state. One of the best junior developers I had the opportunity to mentor was a 35-40 hour per week developer who consistently day in and day out delivered code. He was dependably consistent and eagerly took advice without ego.
