Do not ever let negative emotions or energy linger inside of you even for a second. Once you notice it, flush it out. Fast. Do not “let it slide”, thinking that it is a small and passing thing. The more you let it sit in, taking root in your being, the tougher it is for you to pull it out. Quickly focus on the things that are within your power to act upon. If it is beyond your will, let it go. Sometimes you need to let go of the things that are doing harm to you in order to let the good into your life.
