You actually don't sound lazy to me at all! Getting through college with a 3.4gpa does not a lazy person make. Maybe you are not as driven as you want to be, but it's not a hopeless situation. Don't compare yourself to others if you can help it. Some people are type A and super driven. It comes naturally to them...it's who they are. Some are type B and need to take things a little less seriously...they naturally have less energy but are still great people.

It sounds like you might be rather hard on yourself. It's good to strive for success if it makes you happy. If it doesn't make you happy....spend some time thinking of things that might.

Good luck on everything!
