There is power in the words we speak. There is a reason it is called spelling. When you say things like I'm trying, you put yourself in the energy of try. When you tell someone you will try to be there, you are having an internal battle with the part of you that doesn't want to go. Make the decision, do or don't, just make a choice. As you are decisive you will notice your energy will change. It is a big way to claim back your power.
When you catch yourself saying you should have, if you should have you would have. Maybe you could have but then would you received the lesson?
Trust that you are always where you should be and that even when you make a wrong choice, it's an opportunity to learn faster.
Watch where you use words that make you a victim of the world around you. There is many more than the two I have shared.
