If we set our sites on "beating" another person or company in a sport or business conquest, we can feel demeaned if we don't "win" or can lack compassion and humanity in how we attempt to "not lose". External competition for records and opportunities can be very positive...as long as they don't get personal in the way that the person is lost in the goal.
How to keep things competitive, positive, and personal in the way it is about achieving yourself and not exceeding another person is accomplished by setting goals that relate to self and individual actions. Knowing where your strength, your weight, your medical numbers, your work output, your relationships, and more are now, and assessing them for satisfaction 1st, and potential 2nd, creates a now and later effect, meaning, you have a baseline, and then you can set a goal.
Striving for a goal where you can "win" in spite of nobody else "losing" is a health-minded approach to competition. So go ahead, take a look in the mirror, record where you are now, and get competitive...with yourself, make a plan, achieve the goal of being the best you!
