I have to remind myself of this often. Whether it's my own health and fitness or my business, comparing to others is futile. I have no idea where that other person is in there own progress and each one of us is unique. So my progress is my measurement of success... I vow to be better than I was yesterday and only compare to that!
Do you struggle with comparing to others? Try this: look in the mirror, affirm 3 things of progress or accomplishment and vow to yourself that you will be better today and won't compare your progress with any other person.
