There are a lot of people out there who are unhappy with their careers. Some of them joined the profession they though they would make the most money in or have the best chance at finding a job in only to discover that their work makes them miserable. Others had to settle for their second best choice because of their high school grades, or have seen a profession they would like better than their current one be invented since they've entered the workforce. If, for whatever reason, you're dissatisfied with your career, you should consider going back to school to change it. You can read all about continuing education here.
Continuing education is just a fancy name for adults going back to school. Some do it because they want to upgrade their skills and others want to change their whole careers. The problem is that university and colleges are the traditional stomping grounds of young people, and many older people are intimidated by this fact. Some even decide not to go back to school because of it. But you shouldn't be afraid to stand out. There will be more older students there than you may realize, and you're under no obligation to live in a dorm and drink at parties every weekend if you've got a family to go home to.
If you couldn't get into a particular program out of high school because your grades were poor, you can have another shot at it as an adult. Adult students who are returning to school after a prolonged absence from education have different entrance requirements than students coming straight from high school. Your high school marks will no longer be relevant. Instead, the registrar will want to hear about your life and work experience (and, of course, your ability to pay).
Returning to school as an adult still means you have access to federal and provincial student loan programs, and that it doesn't matter whether your parents are rich - it only matters whether or not you can afford to pay your own tuition. So don't let a lack of money stop you from upgrading your education or career skills. There are even employment insurance programs available for career retraining if your current profession is obsolete or has few job opportunities.
Because a lot of adult students have jobs, there are continuing education programs that you can take at your leisure or at night when you're finished. It does help if you have a spouse or significant other who can support you while you study, but it's not essential. And your new financial and educational adventures could make great blog material.
