In our life, we often regret what we did and which we couldn’t do. Actually, it doesn’t benefit us at all. As for most of us, we missed many chance to earn more money, to get a high position and to realize our dreams. We often regret that we don’t seize those opportunities, thus feel upset. Although we do know regretting the Past is no benefit, but we still can’t help doing it
To avoid the problem below, we need to pay more attention to what you are doing now, making us busier and having no time to recall the past. Moreover, we’d better set reasonably goals one by one. Only by doing so can we struggle for our future better.
