Are you familiar with the phrase "beginner's luck?" It is typical for you to grasp very quickly the point of a given exercise - but also to tire of it just as quickly. For instance, if you have been somewhat regular about diet and exercise, you will feel the effects almost immediately. However, that positive effect will also make you feel like it's OK to slacken your routine. Resist this tendency by incorporating more elements into your healthy regimen: get to bed earlier and wake up earlier!
