Every once in a while, we need to "clear" the past so that we can start over. Don't let the past become a burden to the present. Only by traveling light can we go further.

The human mind is like a container. As time goes by, it is inevitable that sediment will accumulate. We should always clean up the sediment in our mind, let go when we should let go, and forget what we should forget. Throw away the burden of the past and refresh ourselves at all times, so that we can have a more satisfying life.
