On Day 1, you decided to get serious about your side business.
On Day N, you quit trading time for money.
Solve for N.
Years. But assuming you are between 1 and N, I don't think you should focus on the time. Instead focus on what the best journey is for you. Each of our journeys are unique. Focus on your tech skills, your soft skills, learning marketing, sales, etc.
Things will fall into place when the time is right :)
