Our life is all about moving forward, the journey into the unknown. As we grow old the past tries to throw a brick. It tries to remind up about our misdeeds and failures. It is not our fault, the brain has been conditioned such a way that negativity hits harder than success.
What matters to some is their accomplishment which can be monitory or appreciation like pictures hung on a wall.
One thing which makes this journey fruitful is being true to self.
