Some people say that it is best to live in the moment. Life is best when you act on impulse. But more often than not, you should really think before you act. Some people never think about that they are going to do or have already done. They don’t care much for the consequences or effects of their actions. These people just want to live freely with nothing to tie them down. I guess this way of living is understandable since you really do only live once. But there are many people who only think about their actions, or lack of, after it has already passed. This is the greatest source of regret. The largest source of emotional turmoil and pain. And the reason for the mind’s invention of the “time machine.” Of course, some will try to fix what they did and many do succeed. However, depending on what it was, there might not be a way to peacefully undo what has already been done.
