As a person who was not born into mainstream "American" culture, who*has always been in a racial classification of "other", I have to approach this forum from another more serious perspective.**I hope that it is received with the care and concern that it is presented.
Whether it is weight, education, class, race, ethnicity, religion, etc, etc.... our lives will always have people in it that do*not supportive and/or are down right unsupportive.* If we hang on to our resentment of those who have mistreated us in one form or another, it is generally not a motivator, but actually a source of emotional frustration, which can lead to both negative physical & emotional health and actually demotivate us.*
I know that it is difficult to let past hurts go, but it is much healthier to focus on those people who bless your life and provide positive motivation.* When I reach my goals... those will be the people that I share my success with, because the others aren't spending any time thinking about whether I succeed or fail, so I will not spend any of my time or mental energy thinking about how what I do might affect them.
Just another perspective to consider
