Purple was the color of royalty, back in the days of the Phoenicians. That's what it represents, to the |elite|.
We are the super-elite, though.
This is absolutely true and the voice of experience.
If you have achievements, no point in mentioning them even to your loved ones, parents and close friends. They will resent you for it, and withhold commendation or approval.
Needing another person's approval weakens you.
Be strong. Set your own standards, and if you still feel the need for self-congratulation, measure yourself against them not against others.
Be your own person. You can rise higher than others' aspirations could ever envision, if you don't measure yourself against the crowd.
I learned this in 7th grade when I whispered something to my best friend in class, and they hated me for it. I learned it as an adult when my parents didn't express approval for my career successes. I learned it beyond adulthood when I ventured into new fields, scored edge-of-the-bell-curve achievements in them that took all of my effort … and yet nobody in my nuclear family even cared. They didn't want to know.
It is better to learn this lesson early, then to not learn it and experience the pain of rejection. You don't need others' approval.
