So why bother, have fun.

Brain does all the thinking and decesion or gets inspired to work hard from the environment.

My brain and all other brains in the world were never created by the me or the bearer. It evolved in the womb without any control or influence of the said person or me. Every person is born with a brain which he had no control or no influnce ever to determine how it should think and act. So the 'not in my control' brain gets influenced by the others brains in the sorrounding environment to work harder AND the sorrounding brains are not controlled by the person bearing the brain either.

So, is it logical to think that we some how control, how we act or think? I say, every brain got formed in a pre-determined way, so are the acts performed by the brain, so is our destiny. All our achievements, hard work every thing again becomes NULL as we die.
