best advice you've ever received ?!

     One time I was so stressed about school and just social life also and when someone saw my they gave me advice .The best advice someone has suggested to me was "Enjoy today like, they're isn't a tomorrow" . To me this means that be happy that your alive today and enjoy the day like today is the last day to live, enjoy and be free from problems. I took this from the person because, they said "your stressing too much" and then they gave me the advice, and I took it because they said it will help me a lot through my life.  When I took this advice , I didn't stress too much anymore.
