Time spent on past is up, why anymore?

Time seems heavy only when we don't have enough to do or when we are stuck with limited to think. So it is always better to be busy. As time flies and we fly with it, we forget how much a time has really passed. And so we also overlook the things that are capable of freezing the time for us. Things get easier, as we get busier. Efficiency increases as availability of time shrinks. We do more and feel freer. We stop to look at the past, only by steeling a part of the future. And yet, some people like to advise that one should take time off from moving, to look at what has gone.
