I think that it can be true that "hard work and success go hand in hand", but it kinda depends on how you define both "success" and "hard work".
As for the freedom thing... I'll just observe that there are different kinds of "freedom". In that earlier thread, I made the point that, as a founder, I have FAR more to do now, which seemingly means I have more responsibilities and less freedom. Well, yeah, no. I mean, I have less free time now, in a sense. But I have more freedom in that I am the one making decisions about marketing, sales, product roadmap, strategy, etc. In other words, by founding a company, I'm at least a little more free to call my own shots. I decide (well, along with my co-founder, so it's not only me) what markets to pursue, what customers to chase after, what parnterships to engage in, etc.
I'll argue that being a founder means both more responsibility and more freedom, even though that may sound paradoxical, given an intuitive notion of what "freedom" entails.
Also, for what it's worth, in my comment on the other thread, I took the parent comment I replied to as using "freedom" more in the "free time" sense, which is why I agreed and made the comment I made.
