When you blame someone you are giving them all of the power over the situation.
You are handing over the responsibility to make the change, and they probably aren’t going to take it.
On the other hand if you take responsiblity for someone else’s behaviour, you are trapping yourself into their lack of discipline and opportunity for growth.
The best chance you have is to hold yourself accountable to what is yours. Your feelings, your growth, your reactions, your choices, and your journey.
Allow the Universe to take care of the rest, it is way smarter than we are anyway.
