Positivity is a powerful concept but not a strategy. Pretending that you have a positive attitude when it is inauthentic is exhausting. And it doesn’t work. When you can’t get think positive and sustain it even though everyone tells you to be positive you feel worse - another failure.
Honor the hurt. Go deeper with it. Own it. Name it. Blame all you want. Realize the shame. Write about it. Journal about it. Tell someone. Get it out. We can release what we own. When you own your feelings, you can purposely RELEASE the negativity. Otherwise it keeps hanging around.
Next, name what you feel you DESERVE - happiness, career, opportunity, love, friendships, etc.
Open yourself with vulnerability to ACCEPT all that is good and that you deserve. It means releasing the expectation that failure and negativity will continue. Be curious about the process. Yes, it’s scary not knowing how the story will end. But so is a life of negativity.
