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!!!
