What's the best advice you've ever received?

It's pretty funny because I got this from a cartoon show "To live life, you need problems. If you get what you want the minute you want it, then what's the point of living?" I was just watching this certain show with my little cousins (wasn't really watching lol was just listening) then I heard that quote and said to myself "You know what? That totally makes sense".

We are all mortal, live for today.
