The truth is, as we keep growing, we find reasons to change our bad attitude. We might think we are the only ones with such attitudes, but are shocked when we come across someone who can do better and talk the hell out of us, I think at that time, our brains reset and it would be like something was thrown at us that hit us so hard. That is the beginning of turning a new leaf.
I took after my dad with his temperament - I can get angry at little things, and flare up without thinking. It got to a stage, where I became one whom they would mock and insult, calling me all kinds of names including being ugly. Lol
No one told me when I decided to change and not get angry unnecessarily. Even though it hasn´t gone completely, I am thankful that it has reduced and I find myself being patient more than getting hot-tempered at the slightest mistake.
