I finding that a lot of people including my self struggle with knowing what is right and what is wrong. No one will make the right choices everytime. We were given these tough choices so we can learn something out of them. In  a lot of tough situations most people will go with their heart not their brain it is just human. Most times  we feel like mistakes are a bad thing. Do they need to be? Do we have to regret and build a wall between ourselves and forgivness? Why can't we just deal with with the consquences that are so minimal in the long run? And just let the lesson of the mistake be built in to our lives to teach others and make us stronger as people. If you were 92 years old and knew you were going to die any day there is no way you  would waste your time feeling regret, guilt or worry over a mistake. So why feel it when your young? What I am saying is everything you face has a lesson to be learnt. If you can't see it in your own shoes place yourselve in someone else's shoes.
