Colonel Harland Sanders is a perfect example of why self-doubt doesn’t have to stop you. At age 65, broke, and rejected 1,009 times with his chicken recipe, he could have quit. Instead, he pushed through rejection until one restaurant finally gave him a chance. That persistence created Kentucky Fried Chicken, one of the biggest food franchises in the world. His story proves that age, failure, and fear don’t define your future — your belief in yourself does.
