We all talk to ourselves every day, HOW we talk to ourselves impacts on our behaviour. A wise man called Lou Tice once said to me, “you act as the truth as you believe it to be”. Put simply, if you tell yourself you are unhappy, you believe it so you will act in that way.
A good measure of how negative your self-talk is, ask yourself “if a friend spoke to me in the way I spoke to myself, would I still be their friend” If the answer is no, something needs to change.
Every time you catch yourself being negative in your head, stop and replace those thoughts with positive thoughts. For example, if you find yourself saying “I am useless at this job”, change that to “I am great at my job, I can do this, I am just having a bad day, and that is ok, I am human, everybody has bad days”.
