Keep Fighting!
Even the king of the jungle gets in fights and has scars when he wins. Does this mean, he's no longer a lion? No. In fact, when we look at him, we know he is a force to be reckoned with, because he has scars and is still living (not so of his opponent since lions fight to the death).
The interesting thing about scars, is that they remind us of where we have been and what we have been through. They can also serve to inspire us, by reminding us how strong we are. When we fight (win or lose), we learn something of value that can be used later. This is especially true when we struggle to reach our goals.
No matter what, you are still a lion. So, keep fighting! You will reach your goals.
