Back to the Future

If you could tell your future self anything what would it be?
I've been thinking about this for a bit and i'm not sure what I could tell myself.
There is a website that allows you to write an email to your future self.. www.futureme.org Years or days..it would be interesting to write an email now and receive 5 years later ..

If you are a voyeur(like me) you can read public entries from others who have gone before us.

So what will you say to yourself?
