Bottom line education is a life long journey that is many times not fun or easy without a specific end point. You need to consider your immediate need to pay bills and how you want to do so, i.e. dead end job, shop rat, garbage man, burger flipper, health as recommended by others, what ever it is. Then consider where you want to go in the future and if your current classes, seminars, work experience, or major contribute to that goal and how it fits into the picture. Don't get to focused to start with and take general classes that will fit into many pictures so you keep your options open so lifes events don't close doors for you or make you take the long way around the block. Also, think about being a life long learner, that means you should always be in some kind of school or training to better yourself even if it is for a hobby. Sometime hobbies turn into successful jobs and businesses.
Here's my long sob story of education and work if you are having trouble sleeping.
I started out after HS playing Army for 5 years, seeing some of those places the Bee mentioned early and learning about life in general. When things didn't match up between mine and Uncle Sams ideas I got into the Reserves and came home with a wife and one kid. I started in community college and taking general classes that would go toward any degree, leaning heavy on a possible engineering degree in the future. I worked all through that full time to pay the bills. It took me 6 yrs to finish the Associate Degree in industrial measurement and calibration (Quality Control). Then over the next 5 years I worked on four different professional certifications in quality, which allowed me to complete on the job market with others in the field with Bachelor and Master Degrees, due to experience and the certifications. I'm just finishing a Bachelor degree in Manufacturing Engineering Technology 20 years after graduating from high school. The 20 year plan is not highly recommended and has at time made things pretty difficult on family. I also just finished 20 years of military service this month with a laundry list of leadership schools that have given me quite a few college credits and finishing as a Sergeant Major.
Hope this helps.
Didn't you start a thread earlier this on the same topic of jobs and education?
