Ambition can be a powerful thing, and this can be used for good or evil. Some of the most ambitious men in the past were those who changed the way that the world works, but ambition that is used for power alone often corrupts the person who has the ambitions. When you set realistic goals and then meet these objectives you will get a feeling of confidence and self esteem that is very rewarding. Make sure that the ambitions that you have are honorable though, otherwise you could end up wanting the wrong things for the wrong reasons. Setting goals is important and those who end up bored do not have enough goals in place. Life should never be boring because there are always new goals to reach and new ambitions waiting to be fulfilled.
