The important thing is to understand that work compounds. If you keep at it, you'll eventually get something useful, no matter how slow you are.
Also, I'm very careful of chasing new stuff. It's easy to think you have to work on feature X right now, and a few months later you realise that feature was useless. If you spend 60 hours a week working on feature X, those hours were completely wasted. Much better to wait a few months and think about the feature before working on it. If the feature is actually important in the long term, a few months later won't make a big difference.
The tradeoff is that any venture like this is usually unproven. Your friends and family will probably not be impressed when you start, and of course launching any business is massively risky. Your spouse may be nervous for months or years. While I made out like a bandit, during that time I was also concerned about being tied to a single source of income. I tried several other ventures that failed, although never more than I could afford to lose.
Yes, time is important - but depth of focus is almost as important.
If you dont have a long runway, then no.
