You define the word success
There is no specific definition of success as you could be a successful sales person, a famous chef or a great parent or even sister. Even the rewards of success are subjective to each individual person: a big bonus from work? Finishing a good book? Watching your offspring accomplish their dreams?
Regardless of your career, you will always define success in your own way; so never be ashamed of what you call success, especially as rarely anyone is perfect in this world and our differences should be celebrated.
