Are you currently building boats? As a hobby, or just on the side?
I would like to tell you to go for it! If you start today, and look back in 5 months, or 5 years - how many boats would you have built? But if you do nothing, in 5 months / 5 years, you will still just say to yourself "What if I had built boats?" "What would I be doing now?"
I'm not saying quit your job, but definitely test it out, an hour here or there - wake up earlier on the weekend. If you really want it, you have to make it happen for yourself!
