They say that time changes things, but you actually have to change them yourself.

Nothing we can do can change the past, but everything we do changes the future.
Things don’t change. You change your way of looking at them, that’s all.
Since changes are going on anyway, the great thing is to learn enough about them so that we
will be able to lay hold of them and turn them in the direction of our desires. Conditions and events are to be utilized and directed.

Life belongs to the living, and he who lives must be prepared to change himself.Have clarity of thought for what u want and carefully choose and decide how u wanted your life to be and work with commitment towards shaping it.I dont say that you will completely shape ur life of how u dremt of but the Best thing is worth trying than not having a look at it, saying Time changes things.But realise that you actually have to change them yourself .

So before thinking to change the world, think of changing yourself and Be what you thought to be.

Its never too late to realize what u wanted,the best time is "now",so go and get it:-)
