Develop your own compass, and trust it. Take risks, dare to fail, and remember the first person through the wall always gets hurt ~ Aaron Sorkin
When you're pursing a dream goal, it can always feel like you're the first person through the wall. Even though hundreds, probably thousands have gone before you in your field, it will always feel like you're the first one through the wall.
But you have to keep going. If you want to achieve your dream goal, you must pick yourself up, dust yourself off, and go through another wall. It's what anyone who has achieved your dream goal will tell you.
Keep on going, just be relentless.
