When people around you are being negative and you're tired of hearing it.. STOP GIVING THEM THE MICROPHONE.
If you're in a situation you can't excape such as your job or your spouse or a bad environment.. use that same microphone to disrupt the person or atmosphere and make your statement
If you're tired of people telling you what to do if you're tired of people all up in your business in your space and in your head stop giving them the microphone the other day some random person in the building I work at said "you walk like you on a mission". stop allowing people to build the foundation for a life you don't want you don't want the job you have you don't want the relationship you have you're well versed in the things you don't want but what do you want???
ask yourself.. are you giving the situations you don't wanna deal with are you giving the people you don't wanna deal with the hammer and nails to build a foundation for a life you don't want??????
