I often find myself thinking about this very same thing. And every time I do, I end up not having to really give up anything at all, except time in order to gain exactly than which I am missing. If anything, we are always trading bits of our remaining lifespan in order to achieve our goals. Whether it's love, satisfaction, or just about anything else that moves us we are always giving up our "time" to achieve things.
This is why I think I probably trade about a good three hours every day of my life to spending time on the internet, when I could use those same three hours to do just about everything and anything else I still have to do or that's pending on my end.
That's just me though, and yes, I am rambling like an old man. :'D
