There are probably many people out there you can name who achieved great success in an endeavor after they were told: you can't do it!, it's impossible, no one would ________ , etc...
One difference between being a success or not is having a goal and believing you can achieve it.
Be True To Your Own Goals is the last point in the Code of Honor.
So the first thing to making the above an actuality is to have a goal. Now that you have a goal, is it a pro-survival one? Not just for yourself but for others. And then are you willing to go through any barrier that may get in your way? If you are, not only will you be true to your goal, you will achieve it!
