Once you did that one mistake. Try not to ever do it again. For example. Lie. You lie once, you tend to lie again. And the next thing you see, you live you whole life with lies. You will see you start to lie everyone around you.
All i can say is learn from you mistake. Everybody lies. I know. But, it can get in you, and you will lie everytime if you dont stopp.
Be true to yourself, then you will start to be true to everyone.
If you once forfeit the confidence of your fellow citizens, you can never regain their respect and esteem. It is true that you may fool all of the people some of the time; you can even fool some of the people all of the time; but you can't fool all of the people all of the time. - Abraham Lincoln
