Pro: You only live once. I've never regretted the chances I've taken and failed. I would have regretted it much more if I didn't take the chance.

Con: Statistically, you will fail. There are people out there with the same idea that are better funded, better connected and can move faster.

Pro: Internet projects are cheap. Infrastructure is cheap. Give me a $200/month budget , I could easily host your typical small software as a service app starting off with plenty of headroom.

Split the difference: Work and work on your side project. Even if you fail, you still have something to add to your portfolio.
