Our thinking determines how we judge a situation or person. We form an opinion based on our personal values. This is completely fine when we remember that our likes or dis-likes are just that … ours.
Make sure you are choosing your thoughts on purpose. This helps you make sure you are creating your best life because in the moment of thought creation you can chose to look for the beauty that surrounds you or only see the negative aspects of the situation you find yourself in and the people you are sharing your time with.
Once you are clear on the facts of the situation – not your values or opinions – you have choices to chose to remain in that situation or shift it.
Sometimes that shift is physical: I get up and walk out, at other times I cannot leave in the moment and must make that shift in my mind: I chose to leave the negative thinking behind and focus on the positive, even if it is just a sliver.
