The most important thing money can buy you is independance and freedom. Some things where already mentioned. And this independance can make you happy. On the other hand, money can also take all freedom and independance away from your life. In this case you have become a misserable slave of your bank account.

But I can completely understand that selling the company you started you built from ground upcan also be kind of sad. And yes, in this case the money that helpfully comes along doesn't make you happy.

Congratuations to Ryan for a successfull exit anyway!
