The future

Some people say not to worry about it for it is to uncertain, others say you should prepare for the future by working everyday for success. I try not to think about the future to much, there is no use in worrying over sometime that was not even happened yet but when I do let my mind wander to the next years, it makes me very anxious and uneasy. What will I be doing in five years...will I still be in school and living in an apartment or will I have a job and be living in a house and making a success out of myself. Sure, I have a degree and some people call that success but I am not doing anything with my life, just waking up everyday going to class, not really learning anything that applies to my life, going to work, making everyone happy, hoping to make enough money to make bills and rent and enough money to eat the next couple of days. Will I ever be able to have a 'normal' 9 to 5 job with weekends and nights off so I can have dinner and and not have to worry about doing my supposed 'studying'. I also wonder if Bill Gates, or some random doctor ever wondered if they were going to make it and do what they wanted to do or if they were always sure of it and knew that in 5 years this is where I am going to be and what I'm going to be doing or if other people that many think as 'not successful' KNEW that they were going to have a degree and be a doctor, physical therapist, accountant, etc and somewhere along the road got a little off track. I believe this is steming from the fact that I have been in school for nearly 18 years and am still there and will probably be for atleast another 3...and many of my other friends are off getting married with careers. Everyone says, in the long run it will be worth it, i just say really will it?! theres not even a twinkle at the end of the tunnel, more less a light!! Will I ever get married, have children or even make enough money to get married and have children. I believe another of my problems is that I have expectations for my future, I want a big beautiful house successful career that I can afford basically, within reason, whatever I want. I wonder if it will ever come?!? I don't want to see the future, just know at least something for a little bit certain that I will not be working a t the Firehouse, or any other restaurant or anywhere near minimum wage job for that matter, depending on other people and what they think is a 'good tip' for my rent and bills. I believe I am giving up hope and am thinking that I should just quit school and get a job somewhere and work my way up the corporate ladder and maybe one day be making $11 or something at Lowes, McDonalds, or somewhere.....I believe I would be much happier, I may not have as much money as I want or be 'successful' in the eyes of my parents but atleast I know that I don't have to worry about studying and making the grade and waking up everyday and going to the same old classes.
