I am in no way affiliated to these and do not want to advertise or anything like that, but,

If you feel you're in a dead end job, and have no qualifications or not very good ones, consider studying with The Open University.

You can study entirely from home, the courses are in many subjects, and range from entry level up to masters degrees. But the best thing is, if you do not currently have a degree, and your income is below a certain amount, the government will PAY YOUR COURSE FEES.

I did this with a Business Studies course, entirely paid for with a Course Grant.

I won't link to it, but just google Open Uni.. It may help a few in shitty jobs or who want to study without paying..

Ive worked in IT for 16 years, quite successful, well paid
nice house,car etc
doesnt give me any pleasure though so ive been looking at a total career change and now i study Hypnotherapy for a year to qualify.
I intend to work with athletes, football teams etc to help them with performance.
I already have the business of a proffessional rugby team.
my courses runs 1 weekend per month and with lots of self study thrown in and outside practicals

there are lots of courses/qualifications you can do while holding down a full time job
if you hate your job that much and are motivated you can do it!

could be a good idea. The good thing is a degree means something. If I were to tell teach my kids anything it would be degree's are good And if they use the term certificate it means they are giving you a useless piece of paper.
