That's great, but how? I don't live in a aplace like London where this might be feasible. Even then I wouldn't know where to start.
I must chip in here.
Not to be a sob story but I've been on my own since school, on the social thro A levels, no financial help after that, totally on my own.
What I learnt was - it comes down to this - only YOU are going to be able to solve this at the end of the day. Yes there may be a million reasons why X or Y solutions wouldn't work in your case, but having decided that, YOU are still stuck in the same boat.
Wherever you live, find a way. Don't take no for an answer. Ask yourself what the person would want in a new employee and then be that. Ask what your own boundaries are in terms of hours, what sort of work, etc etc and work within them - but be aware that, narrow it down too much, and YOU will be the one out in the cold.
I know its hard. But you have a brain that has done you well so far, so sit down and ask some questions about what you want to do, what you are prepared to do, how YOU think YOU will achieve these things, what you best approach ought to be, how to speak to the person, how to write the perfect covering letter, how to sell your skills and experience - and even if you don't have any, thats fine, you chose the interview or whatever so speak about why.
In all honesty, thinking like the above is what has helped me through many a tough and lonely hour. At the end of the day you CAN rely on yourself, and you are going to HAVE to. If you really apply yourself, how can you fail?
