> For me at least, time is much more valuable than money
yes, but 'for you' being the operative word. Your time is worthless to me. Your time, if you used it to do something _I_ wanted done, would be worth something to me. Therefore, it is true for people to say time is money.
But then again, most middle-aged people have a family that needs to be feed etc. You simply don't have that many options. Best thing that can happen thus is that your passion becomes profitable.
