I remember waking up every morning excited to check the balances for everything. At most, maybe $10.00. That slowly brought me to depression. I was working 12+ hours per day on every thing, but had nothing to show for it. I did this for ~3 years (although I've been building things for 10+ years). I worked as a freelancer to earn real money as well.
Eventually, I just had enough. Got a job. Started letting domains fade away (I owned perhaps 50+). What a tiring lifestyle!
Nowadays, I will not build in the hopes of becoming rich. I'll build things I want to exist - things that I will use personally. Sure, I'll slap a price on it (as you can see on leetchess), but by no means am I trying to retire from the income.
So, maybe don't give up in the sense that you no longer build. But perhaps it's worth evaluating why you build.
