I hope so. I think negativities about our past won't help at all. If we made vile errors and mistakes, we should take it as positively as possible for days ahead and try to learn a lesson for the brighter future. As if something bad right now can be a blessing in disguise someday, we have to say never say never for our failures. Smiling about the past gives us affirmative attitudes and sentiments for what we did and it can be a good starting point to do the next thing. As you know, life is full of ups and downs for everyone, which is no exception. Therefore, having a positive estimation on your life is no option but a must .On top of that, in this regard, we also need to have a mercy on others' mishaps as well as ours.
