Do you often find yourself in a quandary about some problem that actually is not directly concerning you? Are you mixed up in someone else's life?
Your adult son has decided to quit his job and join a band. You tell him that you don't feel that this is a good idea.
Someone at work said something to a fellow employee and you are outraged. You take it upon yourself to try and straighten it out.
You think that your daughter's boyfriend is far from marriage material. You tell your daughter that she could do better.
These are 3 examples of being is someone else's business. Once a person has reached adulthood, what they do is their business. They are on their own path, they need to make their own "mistakes". Even if they are your children, your time is up... you have done all you can, they need to be treated as adults now, not controlled, like children. Even if you think that you know what needs to be done, or what would be best for them; it is none of your business.
"If a train doesn't stop at your station, then it's not your train."
Just think how much more enjoyable life would be without having to worry about, or control what everyone else is doing. You only have to worry about yourself and what you are doing. Your business is to make yourself happy, period. If you are happy, people will want to be around you. One way to be happier is to let go of control....control is an illusion; you never really have control over any situation or any person. Let go and live YOUR own life.
I am certainly not saying that you shouldn't be considerate and supportive of others, but that is where it needs to end. Do not jump in the middle of someone else's life.... live your own.
