Uh, I often think about what my life would be like if I'd heard of Bitcoin a bit sooner. I had a pretty badass gaming pc with a pretty badass GPU back then, and I'm pretty sure I'd have been able to farm a considerable number, enough to last for a long, long time.
Unfortunately now everything's harder, and as you've said yourself, one should think about investing. Investing requires something I don't currently have: MONEY! But yeah, I agree with the bottom line here, it's better to do something today than complain about it later.
