Freedom. The start of life is long and boring and it's pretty much a straight path where you don't have much choices. you have to go to school, and finish that path. But after all that part of life is done, then the rest is yours to chose and do what you want with it.
Having my own house and a job, and family, I could not really ask for more. I have it made. I worked hard for it, but it was well worth it. From this point I can choose my path. Maybe I want to change careers, or start my own business, or just keep doing what I'm doing. The choice is mine and only mine. Life is all about what you make of it, and it's up to you to make the best of it.
Some people live to work, I work to live.
