Past issues are our learning points... Time can't be reversed ,so conducting all kinds of post mortem is all nonsense.. Future is a concept, nothing real ,pure imagination.. Instead of dwelling in past mistakes and future imagination,we must try to remain focused on what do now,here and today's targets and goals should be pursued with energy, excitement enthusiasm and zeal.... WE shall be happy and satisfied,if can finish all the jobs at hand to further our goals and objectives for this single day...
