When I was a college grad and in my 20s, I would constantly work on side projects, building a startup and consuming as much knowledge as I could find about new tech. I remembered when the iPhone came out, I would spend every minute of my commute learning about how to build an app.
Now that I have a family and am a bit older, I feel much less ambitious. I no longer feel the desire to build a business, or hack on side projects. Granted, a lot of this is because I have less time, but even at work, i feel absolutely no desire to learn new things, or get a promotion.
Is there any way I can revive that ambition again?
