Your time is limited, so don't waste it living someone else's life. -Steve Jobs
This is a pretty great quote, isn't it? I think it's easy to think we have a limitless amount of time. Even when we realize that we don't have an unlimited about of time, we can often live like we do. We forget that the days we are given are a gift that we have.
There are things that seem to take away the gift of the time that we have. Sometimes we feel as if physical & mental illness have robbed us of what our time could have been. Sometimes it's a relationship that seems to have robbed us of our time. Sometimes it's something beyond anything that we could control.
One thing that shouldn't rob us is our own decision to live the life of someone else, and to give over the control and power of our lives to another person. Being healthy in life involves, in part, having healthy boundaries. Remember that having boundaries means that we are responsible for our own thoughts, feelings, and behaviors. When we try to live someone else's life, we are not being responsible for our own "stuff" in life. When we live someone else's life, we lose out on the life that we have. We miss out on our own strengths, gifts, talents, and unique abilities. More often then not, we aren't content or happy either.
Don't waste your time trying to become a different person. Embrace who you are, your gifts, and your talents, and try to make you be the best person you can be!
