external motivation

I wish I was one of those people who had decent internal motivation, that inner drive to do things and set goals and have accomplishments. I feel like I would be far less frustrated with myself if I worked this way. 

As I am learning, I do better with external motivation. For example, I've been trying to go th gym for the past two mornings - could not/would not get out of bed in time. This morning, because of the bet with my coworker, I had no problem. I love to be praised, though, I don't beg for it. I just know I work better when it is someone else's expectation for me, or goal for me. 

It's really frustrating, and I'm realizing I need to switch that around a bit...
