Dedication and Commitment

When beginning and exercise program you must determine your level of dedication and commitment. How much do you want it? To what levels are you willing to push yourself? What levels of pain will you endure? How important is all of this towards reaching your goal(s)?
This young lady made such a commitment that I can only marvel at her:

Alexis Page trains under a friend of mine (Wendy Hilliard). She has determined that she will endure a 2+ hour trip (each way) to her facility. She will endure 4 hour work outs. All of this is because she wants to compete in the 2012 Olympics. She still has her education in mind- She is an A student.
My own training brother (Sifu Michael Aronson in Houston) has a 16 year old student who travels 60 miles each way to train with him.
How far (physically and mentally) do you wish to go? I wrestle with this quite frequently. After suffering through a horrible year in 2002, I lost a lot in my general fitness level. When I finally came out of the fog from that year (about 3 years later) and saw how much I had lost, I had to asses how much I wanted to work to get it back. Many questions came/come up (I still haven't resolved this fully!):
1- To what level of fitness do I want to get back?
2- How hard do I want to train?
3- If I wish to get back to my earlier levels, HOW do I motivate myself?
4- Can I get there?
5- Can my body handle it?
6- I have done all of those hard work-outs, why do them again? I don't have anything to prove!
It is on my mind during every work-out.
The key thing here is that I still work out. While I am doing this I will push myself each time. If I get to a max level, great, if not, at least I did my work-out!
Many people make excuses for not exercising; They don't have the time. They don't have a gym. They have too many injuries. If a 12 year old girl can travel almost 5 hours per day and still maintain her grades (watch the video, she is a well spoken and well mannered young lady- I KNOW Wendy wouldn't have it any other way) you can find the time and make a way to exercise for, at least, a half an hour! You probably aren't going to the Olympics or, even, be a Kugn Fu master but if you don't exercise you won't be working enough to afford the health care that you would need because you lost your health from not working out!
