What other people think of you is none of your business.

Externalities often take over our emotions and waver the strength our decisions. Many times, you probably made a decision on something, and then hear that someone said something negative that might waver your thoughts about the matter. Human beings are extremely weak and fragile when it comes to making decisions and keeping to it, particularly when the "noise" in the surroundings do not have a clear idea of the circumstances that you are into. Remember, only you have the clear details and information of what has happened - do not allow others to cloud your judgement or affect you emotionally.
