We all have different ability that lies in our strength and that some see as weakness. I can do it better than you can doesn't mean I am lording it over you but it means that I know my strength and I feel that it is my area of specialty.
Some people feel let down when people ask them to step aside form a particular cause or project and they start feeling depressed or they make a scene by creating havoc. Well it's not that difficult and complicated, it is just a way of telling you to build up on that side of you or learn from the person chosen to replace you you.
Not everything is to be an issue, some things are better left untouched/unsaid where you make a major step by investing in yourself and putting to shame people who feels you are not capable of handling that thing and this is what you call purpose. Never derail from your purpose, there might be a setback for a while but then things will come out nicely in the end.
This is teaching us that our purpose is our brand,learn to build and develop it. Your purpose is a solution to problems that you will tackle continuously until it ends. Some of our purpose are sitting on unhealthy foundations, we need to focus on it by breaking it down for rebuild.
Purpose is key and never forget to always evaluate yourself about "what you are doing"? and "where you are going"?. So many people just go with the flow and this is like marching to the band without following the rhythm. Do not be a motion without progress always evaluate everything including your success because by so doing this, you will continue to grow better.
You cannot build a great building on a weak foundation, you need to remind yourself daily that you need transformation (branding) to rebuild your life. Brand yourself and your purpose and the things that you see as barriers on your path now will be a mere stone. When we are seen as the best in our field, they will move protocol for us too.
