"...according to a pocket dictionary, the word "pink" is defined as excellence. And to be honest, I really love this definition because it challenges me to be excellent. "
One misinterpretation to excellency nowadays is being the highest and the best but excellency does not only mean being on the top but meeting the top. According to a web definition, excellence is defined as the quality of excelling; possessing good qualities in high degree. Being in high degree does not mean being the highest. Not being the best but giving our best. It is not necessary that you'll be the only one, it may even mean being one of those who are excellent.
Excellency can be reaching over one's own limitations. We all have our own limitations and meeting them is very difficult, but reaching over it we'll be the hardest part.
To be excellent, we should know our strengths first, or we can call them talents and abilities. Then, we should also know and accept our weaknesses because this will define our limitations. We, human beings, have our own capacities.
Now, differentiate your strengths from your weakness. Rather than focusing on your weaker part, focus first and nurture your stronger features. Cultivating your talents and abilities will lead you to excellency. Don't concentrate too much on things you can't do but instead do the opposite. You'll only get frustrated if you do so and the saddest part, you'll only look so trying hard.
And this is what I want to emphasize, you can be excellent but it doesn't mean that you're the only one that can do it. Accept if someone else, can also do the same thing you can do. Remember: You are UNIQUE just like everyone else!
