I've felt like this many times in my career, especially when work gets hard. One thing I realized though is that one has to do what he does best. If it's selling a web-app - that's fine. Look at Elon Musk - he sold PayPal and then went on to use the money to fund world-changing initiatives. You shouldn't underestimate how many smart people there are working on world changing initiates, even in places like university labs. Unfortunately world-changing research doesn't pay well. Elon Musk on the other hand is a great example of hacking the system - making money the capitalist way, and then fund initiatives you want to be remembered for. It's a risk-reward trade-off of course, but something tells me if you'd think you could walk away with 100M in 2 years from your startup and use the money to solve the world's water problem - you'd probably do that. As usual it just comes down to your estimate in the gains in your startup over the next several years, versus what you think your time is worth.
