For me, founding and building a business have always and fundamentally been about freedom and self-realization. In effect, owning a business allows you to do and try things you otherwise wouldn't be able to. It lets you crack your head against the proverbial wall of reality and try to make a dent in the universe. It lets you rev your engine to the max and push for something with full force joined by a team of likeminded. To me this is the key to feeling happy and knowing that I am contributing in a meaningful way. The price for that freedom is massive commitment and sometimes risk.
