Take the time for daily, even hourly, positive affirmations. Compliment yourself on being stronger, leaner, smarter. In Gold's Gym, Venice, the most shining and extreme example are David and Peter Paul, the popular Barbarian Brothers. They have taken this idea and taken it to the next level, forgoing typical gymwear for flannel shirts, jeans, work boots and a Barbarian attitude. They've even turned this persona into a full-fledged career.
Physical change is an extremely challenging endeavor, fraught with many joys and many tears.
Approach fitness and every endeavor not with a negative 'must do' attitude, but instead look forward to the challenge of stretching your Limits, and the challenge of solving the problem. Don't run to a personal trainer and ask, hoping he or she will answer your question quickly. Buy a book, go to the library, look more closely at your eating and exercise habits. Solve the problem yourself. Many times individuals look at the details of an endeavor without having any idea of where the detail fits in with the big picture A thorough understanding of any undertaking is necessary to inspire confidence in yourself and your abilities.
