Tristin believes that self-esteem comes from the worth you assign to yourself, rather than the approval you get from others. She wants to help young women realize this because she wished she would have learned it earlier.
She also believe that you should always prepare the best you can so that when opportunities present themselves, you can take full advantage of them. Also, give yourself permission to fail, because it will help you learn and do better.
At the end of the day, Tristin wants to look back and remember everything she accomplished and tried, even the failures. To her, the biggest regret would be to not take advantage of an opportunity out of fear of failure, rather than failure itself. Great advice!
