Our attitude determines our altitude in life. When we experience failure or things do not go our way, we do not have to let it bring us down. Obstacles are not a reason for us to give up, but rather an opportunity for us to learn, to grow, to become something greater than we were before. "So what if my manuscript was rejected. I can write another one!" This is the spirit and mindset of champions; one that acts as a catalyst for personal growth and success.
Writing was a driving force for Anthony Trollope. It was something that he most likely could not have given up even if he wanted to, for he had a natural talent and ability and he was very dedicated to his craft. It was this level of commitment that allowed him--or perhaps forced him--to begin a new novel immediately after being rejected. For you see, that level of commitment to any art helps us to find strength, courage, and determination to persevere in even the most unfavorable of circumstances.
Each of us will face obstacles and setbacks in life, for we are all sailing our vessels at the mercy of the sea. But if we let the storms of life hold us at a standstill or dissuade us from continuing forward, we will never reach our desired destinations. If, however, we espouse the right attitudes and keep our eyes on the prize, every setback, obstacle, or failure will become a chance to grow stronger--to learn valuable lessons and discover areas in our lives in which we might improve and do things better. With the right attitude, adversity essentially becomes a fancy word for growth opportunity.
