Do your best and let life do the rest

I came across this line and liked it immensely. Decided to write some lines on this. As a kid in school,we used to get some one liners and were asked to write few sentences on it.
What this means is that we need to put in the best of our ability but we should not think of results. Life will respond back if our efforts are sincere and honest. May be some dreams are unfulfilled.Sometimes luck does not smile on us and our endeavour are not rewarded. Sometimes one gets to a point where one knows that nothing is working. It's not about losing hope. It's about trusting life. Millons of people have come to this earth before us and millon will come after us. Each one had some wishes fulfilled & many unfullfilled.It's not easy to let go of what you want. But why wouldn't you if something even better is waiting just around the corner? Hope for the best and do work to the best of ability. Have faith in almight's justice.
