"Don't be distracted by criticism. Remember-the only taste of success some people have when they take a bite out of you."- Zig Ziglar
One of the things that we all must develop in order to survive the gauntlet of extreme success is to grow a very thick skin.
That doesn't mean being a jerk or arrogant. Instead, what it DOES mean is having a knowing that you are on the right path and doing the right thing regardless of what some negative dream stealers may say about you or what you are trying to accomplish.
It can be tough to hear negative talk about yourself or what you are working to accomplish. This can be especially challenging when the person is close to you like a long-term friend, family member, or even the person sleeping in the bed next to you.
Have compassion for these people. Realize that they are only projecting onto you their own doubts, fears, and feelings of hopelessness. Also realize that before it all said and done you will be a hero and champion for many of them because you will show them in the flesh what is possible.
Still others will never see the value in what you are bringing to the world and will always be negative. Let that be their problem; never let it be yours.
So grow that thick skin  and continue to build, build, and build until you wake up one day living in your destiny. And when that day comes, none of the challenges that you are facing now to get there will even matter. I promise.
