Forget regret, or life is your's to miss...
The only way I can describe myself is unique. I really feel that in life people need to smarten up and stop being ignorant, arrogant fools. Once we set aside our arrogance we can realize we need to be generous and empathetic to people and their struggles in life. If there is one thing we all have in common it is that each and every person has their own struggles.
It is important to remember that whilst what you do to another person may only affect you momentarily, there is no way of telling how that is going to affect the person in the long run. Sometimes a friendly smile can make a world of difference. We all have trouble with that.
Just remember that actions speak louder than words, and inaction can speak even louder.
