That's the best thing that can happen to anyone, to turn his/her hobby into a job or profession. When I saw your post, I was quick to remember the popular tech YouTuber, Macques Brownlee (MKBHD), it grew from a hobby and easily into a job, and I'm sure he still sees it as a fun project everyday of his life.

We can't all turn our hobbies into jobs, but if one can try, it will always be worth every time and efforts.
