Side Hustle/Learning to Code - Full-time Job

I recently finished the throwback episode on the Indie Hackers pod with Lynne Tye. She's incredible! If you are looking for inspiration or upset that you quit - this is the episode for you. There is no shame in quitting. Quitting is a common theme that pops into my head from time-to-time when working on difficult projects. It happens to all of us at one point.

Let me get to the point... I want to start a side hustle to generate income while learning to become a technical product manager. I want to create something great to help alleviate a problem. I'm married with one duaghter and have a great job. My time is very valuable. Getting up early (5am) and going to bed late (11pm) is a must when wanting to succeed.

I'd love to hear your feedback on how you manage your time (to build/code). How do you get passed the idea of quitting?
