I came across this thought last week. It is a great reminder to focus on your goal, and not let negative thoughts distract you.
A frog decided to reach the top of a tree. All frogs shouted, “its impossible, its impossible…” Still the frog reaches the top…How?
Because he was Deaf…and he thought…everyone was encouraging him to reach the top.
Lesson: Be deaf to negative thoughts, if your aim is to reach your goal!!!
