~ Albert Einstein
Everything must be understood at first before you can get the results you want. I truly believe this peace comes from within first. If all people would look for that peace inside of themselves, they would be so much more ready to enforce it in the world around them.
Life is truly an opportunity you get just once. You make the best out of every situation. If there are challenges, then go deal with them. Overcome the sorrows and play the life role you always wanted to play. Life is you. Life is the adventure you dare to live. So do it. Make some peace :)
