What are you afraid of? Are your fears tangible like spiders, rodents or clowns? Or intangible like trying something new such as a job position or entrepreneurship?
What is it about fear that keeps you at a stand still? What holds the key to the lock and chain? Is it trying once and failing or trying multiple times and failing? Have you tried so many times that you have given up? I hope not! Babe Ruth said, "it is hard to beat a person who never gives up".
I encourage you to be that person that never gives up. Be the person that is always "UP or Getting up!" Be the person who doesn't allow FEAR of the past to control the future. Yes you could fall again! Yes it might hurt! Keep getting up! You never know when you are one try away from success. As humans, we have only one life to live. I hope you live yours to the fullest rather than say, "I wish I had..." you will say, "I'm so glad I did...!!!" You can do it!
