Even if you are the least skilled person on Earth, you can scale great heights of success through sheer confidence and a belief in yourself.
A confident person is one who minimises doubt and hesitation about oneself and is ready to face his or her fears head-on. A truly confident being will not even let failure touch him or her, taking it only as a learning lesson and moving on. Repeated failure might introduce the element of doubt in a confident mind, but someone who knows the importance of being confident to take the first step again rebuilds himself/herself and tests waters yet again, knowing that he or she can be scalded, or not, the nth time.
It might be the worst that has happened to you, and you might be so broken you need plenty of time to get back on your feet again. Confidence is the building block of the foundation you might have to lay again to find you. Find it. Use it to keep your chin up and fuel those spirits that keep you alive.
