On optimism

Talking to a friend other day about mental attitude towards problems we face ,we reached a conclusion that how we approach problems is more important than problems themselves .If we can't really change everything ,we can change a lot ,but with a proper mental attitude .Problems and conflicts are unavoidable  but our mental attitude is our own choice .BUT that's not it.Well, not that simple ,we all go through problems where nothing seems to work and that is a phase of necessary experience making us grow stronger .As research proves -dangerous , odd  and tough new situations activate set of genes that make our brain grow more intelligent and wise .So this necessary experience is not of no worth ,as Nietzsche would say ,''that which doesn't kill us,makes us stronger "
