It is seriously tough. For a few years I was pretty much hospitalized constantly. Because of this I've only been able to work since fall...and then I got sick again I was hospitalized for another 2 months, and have bee recovering for two months. I've got a few things from family because of this but now if I want anything I'm on my own. I'm explaining this situation because for me, making cash is hard as hell, so I've recently been doing a lot of thinking on how to save up for photography and for my portion of university fees.
Budgeting is key, break out that excel spreadsheet and start planning and checking on how much money you already spend, and how much you can save. Cars are deadly, I say don't get one, I'm two months out of a serious bowel surgery and I bike everywhere to save cash, I think you can too. Get a job, or two if you can and open up a bank account with good returns which you specifically NEVER TOUCH (until you want that new camera, but that is what this account is for, saving for big things). Never eat out, or almost never, bring packed lunches, learn how to cook (the ladies love it), and be a leech if you have to (you can make it up to your friends by cooking a fabulous meal for them with those cooking skills you're picking up). Lastly, find a few other ways to make cash outside your job like babysitting, dog walking, blogging (I'd really like to hear about this payperpost thing?), and of course if you can, photography.
I was pretty cavalier about my cash when I first got a job because I hadn't had any money to spend for 3 years, but I regret it now. The most important thing is planning and making a few sacrifices (get good equipment, but get it used, and maybe get it only once a year). Now if I can only properly implement this plan myself...
