When trying something new, you normally get a feeling of fear or hesitation. The feeling is enough to drive anyone away but you have to be stronger. You need to let go of the negative feelings and take the chance your dwelling on. Once you do, you have a feeling of adrenaline and happiness which is enough to get you to do it again. Then comes comfort, and the things that once brought you distance and fear no longer have that hold on you. Then you become unstoppable, then you become free.
Take the chance.
