Do not get upset with people or situations, both are powerless without your reaction.
No matter what is thrown at you, no matter what you witness, your reaction is what starts the domino effect that could be the determining factor in the outcome. You have a choice of what takes place ... it all depends on how you handle any given situation.
Frustration and stress come from the way you react, not the way things are. Ask yourself if you'd rather always be right or be happy. If being right wins, then you are one that needs to stop, look and listen before you jump in the middle of anything that is going on. Nothing can or will happen without your reaction.
There will be no drama, unless there is participation. Every situation does not require a response. What if there was a war and no one showed up?
You don't have to attend every argument to which you are invited.
When you challenge every situation it doesn't do you or anyone else any good. Mind your own business and let people handle their own 'stuff.' It is not up to you, you cannot control or save the whole world. Just walk away and watch what happens. The situation may just dissolve or it may explode, but at least you're not in the middle of it and don't have to answer for it.
"Life is 10% what happens and 90% how you react to it." Charles Swindall
