If what your life purpose is not achieved at the age of young to old, what do you do with your own life purpose is not yet achieved it 
? Forward or surrender to circumstances,
The only way is forward. To victory! If your purpose is important enough to you, go for it. What is your purpose?? Forward or surrender to circumstances,Not everything you want is you can achieve. It doesn't mean that you fail once or twice or many times that you don't have any purpose in life. God bring us in this world because we have a purpose. It is up to us how we'll discover it. So get up and move on. Move forward. Do not dwell on the past.
