> The trope of "money doesn't create happiness"
It's not a trope. It's backed by research. As an earlier poster says well-being research suggests the perceived increase in happiness plateaux after some figure around $75k. In fact, too much money can isolate you from your friends and family who stop being able to relate to you or feel you always have one over on them, or you move to a posh neighbourhood in a massive gated house and no one comes to visit any more...
> fills me with dread. For me there isn't much of an option beyond becoming successful as an entrepreneur
Utter rubbish. You should take this course. Believing that the only way to be happy is slogging your guts out on a moonshot to become a multi-millionaire is a sure way to stress yourself out and become unhappy.
There's more to life than money. In our industry it's easy to make more than enough for a comfortable life. Many people I work with take large breaks from work. That is real freedom. What would you do if you made all that money anyway? Maybe just start doing those things as soon as you can - you've got to find something to fill your time, either working for someone else or doing things that interest you.
> Having to work until 65 running a mildly successful business that I built seems like it shoild be much more gratifying than slaving away to enrich others.
That may be true. But that statement sounds like you wouldn't be doing it for the money rather the intrinsic satsifaction. That's far more valuable after you've hit that point of not worrying about bills, etc.
