Indeed, there is a strong educational principle that goes broadly along the lines that “If you haven’t made a mistake, then you haven’t been trying!“
In light of the fact that we all make mistakes, isn’t it curious that people are very quick to judge. And they often do so without first considering whether they are as good as Mother Theresa or whether their life is as pure as the driven snow. Just think the words in the Bible at John 8:7 along the lines “He that is without sin among you, let him cast the first stone“; not to mention the old saying “People in glass houses shouldn’t throw stones.“
One of the common causes of depression is dweeling on the past, missed oppotunities, or the chances we never took. Whatever your past, forget it and move on. Why let it cast shadow on your present? Only you can bring happines to your present and future. Your in charge, no one else, so take control.
Past relationships, past failures, past mistakes, past memories are the past, not the present and definitely should not define your future. Many relationships fail by looking back on past sins- smile sweetly to yourself and remember how much fun it was at the time! And if it was not fun then remind yourself its the past and focus ahead, not back!
This is the key to happiness.
