Putting on hold hobbies to build business?

There are a couple things I'd like to do (particularly, learn a new language and learn to draw). I'm putting this off though until I get to a certain level with my business. I'll still do relaxing hobbies like meditation and netflix.

Does this make sense? I mean, people with intense jobs with lots of hours often just work-eat-sleep. If I was able to take that perspective right now I think that would be good. Not for the rest of my life, but right now yes.

What do you think?
