What do you live for? Your strength? Your love? Your entertainment? Why do you live for these things? Nothing is meant to be so fully dedicated to. Not an entire life. Because after you are gone, the strength you held will fade, the love you harbored will wilt, and the entertainment you witnessed will be all but forgotten.
Strive for something that will stand without your help, without your life. The only way to fully achieve remembrance and the only way to truly set the world on a better course is to leave something behind that inspires others. So instead of only strengthening, loving and witnessing, use such gifts made by others to forge your own legacy. Make the mark upon the world that will never disappear. Find that mark, and you will know true happiness.
