So basically, what is done, is done. Don't regret, move on with it because the broken had been done, you can't turn back time. Find the solution and learn from it. People make mistakes. But don't be afraid to make mistakes. Learn from your mistakes and vow to not wanting to repeat them again. 

Think before you act. An easy statement that is hard to obey. I often found myself guilty of committing this crime through words. I may utter a very ridiculous statement without thinking, just for the sake of "reasoning"(alasan). Tak bagus, tak bagus.
