Here is an interesting thought for you. Have you ever sat down and written out what IS your job? What your purpose is, what your objectives are, by what you would like to be remembered?
Here are some of mine as thought starters for you.
To live an ethical, sane, productive, enjoyable and helpful life.
To help those with whom I come into contact to live a happier, healthier, more productive and effective life.
To keep my body in a fit and able condition for as long as I wish to use it.
To set a good example to those in my circle of contacts.
Not by any stretch of the imagination am I perfect at them but I am better than I was and still improving.
