Fear will always exist, fear is a warning sign, it is a basic defence mechanism of our mind, but it is also a mechanism of support, of impulse, because fears are conquered, they are conquered.
Don't let fear stop you, use fear to your advantage and no, I don't mean that you do things without thinking, but sometimes we just sometimes don't need to think too much and take a leap of faith.
We are capable of many things even those we think are impossible.
