Some guy I knew asked me if i could write him a programme to help manage his clients' investment portfolios. Because I was too young to know I was in way over my head, I was able to complete the task and do it well. Pretty proud of it, actually; 16 bit windows (3.1) and the code was rock solid. I figured out on screen graphing, good db design, reporting (I wrote all the reporting and printing libraries, incl basic graphs (pie, line and bar)) etc etc. Now-a-days that sort of thing's a lot easier, but back then there was very little. oh, and no internet either, just the local bookshop.
