Be afraid! That's when it means something to you.
The fear of starting;
when you want it but you can't have it, when you fight for it but you still lose it but that's not way scares you, what scares you is that voice that tells you to try again.
The fear of failing;
when you have it and it all starts to slip away, when all your victories start to unravel in front you and the thought of losing it all grips you so tight.
The fear of what would come after you succeed;
when you're at the top and you can't remember what the ground feels like, when the battles over but you're the only one left standing, when you shine so bright you can't see anyone else...
So be very afraid, that's when it means everything to you.
