It's not that life always goes smooth to anyone.
It's not that the one road has only trees and flowers on right and the left, rocks and numbers of obstacles will always be there.
It's not that having a peaceful mind for 24 hours a day is the route of happiness one have to go through, it's what gives pain to our minds is what making life more reasonable and much fun.
It's the process of getting strong enough by facing all challenges and overcoming them while preparing oneself mentally and emotionally to be ready most times for whatever comes to life. It's not easy to live a good life, it's not also hard to do when you open your eyes widely enough to face what's coming into you bravely. Fight yourself for your own self.
