Don't underestimate how difficult and stressful it can be, even for established artists.

This x100. I feel very fortunate and lucky to be able to have my bass earn my living for me. It's bloody hard and you should treat every day like you're setting up your business for the first time. But the rewards are worth it.
I'd say for anyone wanting to go down this route, do not place all your eggs in one basket. Use your talents and skills to form multiple streams of income so when one dries up (which it most definitely will) you have something else to fall back on whilst you fill that gap.
