Yea taking a leap of faith is very important . Many things we could have achieved but were too scared to try. Life itself is a risk. The fact that you never know what's gonna happen the next minute you leave you house yet you leave is you taking a risk. The only difference between you leaving your house on the morning not knowing what would happen and you failing to attempt that feat is simply the presence of fear. When you want to leave your house in the morning, you have no atom of fear and so take that risk with joy . But when fear creeps in, you find yourself not being able to do that which you would easily do on a normal day. So I think we should try to fight off fear at all times and tell ourselves we can do it even when our whole being disagrees.
