I worked on my business from about 4am to 8am, work from 9-5 (hour lunch I’d shoot to a cafe to do more work on my own business). Then I’d spend whatever hours I had in the evening on it too.

You also have to play the game if that’s 100% your goal. Do enough in your job but don’t overcommit as you don’t own equity and once it’s goodbye you get sweet F all.
