“I deserve better”
One of the most corrupting pathways to walk on.
When you say you “deserve” better, is it a demand or a complaint? Who are we complaining to when we are the writers of our own books. When you are careless in a relationship or while driving and meet with an undesired consequence; it was your own decision to be careless. You deserve what you get. Always.
The better road to walk on is the one next to it. What can I do differently now? Think about your past. Mistakes you have made or opportunities you missed. Think about what you lacked. Skill? Attention? Or may be something else. You are not the creation of your circumstances; you are the creator. Start acting like one.
