Best advice I've ever received

I have received a lot of advice and some you do and don't want to hear but need to hear it.
  1. I think the best advice I have ever gotten was to just stop worrying about every little thing that happens in my life and let it go! I would beat myself down and fight as long as I could for certain people and things in my life. Once I started letting them or it go life felt a million times better! Do what is best for you!
