Who has ever done some thing they regret and want to go back in time and fix it. But one can not do so it is much easier to accept the fact that once it happens it is irreversible. The only thing one can do is accept it and focus on the future. I myself have contemplated how to fix something I have done in the past, but the conclusion is to accept it and make sure that I don’t commit the mistake again, and focus ahead. It makes no sense to live life with regrets and without making mistakes. If your life is immaculate there is no risk and the greatest pleasure in life is taking risks, taking chances, not knowing the outcome. So what happens, accept it and look forward. There is a reason why the past belongs behind.
The most somber emotion some one can feel is the loss of someone or something. Nothing in this universe lasts forever. From something as big as the sun to something as small your favorite pair of shoes. From something as indispensable like people you love to something as empty as your cell phone. Nothing in this world is everlasting no matter how well guarded, how healthy, how resilient. Not even thoughts or ideas, which are thought to be untouchable to external forces like time and age. We must accept this as fact.
