The key is to connect the work they love with something that other people also love. Not everything you love can be turned into a successful business. I used to play video games, and no matter how good I was at Halo, no one came along to give me a check. However, I later learned that there were *other* things I loved -- international travel, creative self-employment, writing -- that I could in fact monetize.
Instead of spending hours playing with accounting software, dreaming up potential expense and income categories, and creating fancy reports with no data, spend that time generating revenue. As long as you record everything you do now, creating a more formal system later will be fairly easy. It will also be more fun, because then you'll have real data to enter.
Often, banks that aren't willing to work with you based on your financial profile become more amenable if you suggest working with an SBA loan guarantee; these loans are guaranteed up to 90 percent by the SBA. Small businesses simply submit a loan application to the lender for initial review, and if the lender finds the application acceptable, it forwards the application and its credit analysis to the nearest SBA office. After SBA approval, the lender closes the loan and disburses the funds; the borrower makes loan payments to the lender.
Small businesses have a tougher time getting approved due to factors including lower sales volume and cash reserves; add to that bad personal credit or no collateral (such as real estate to secure a loan), and many small-business owners come up empty-handed. Getting funded takes longer than other options — typically two to six months — but banks are usually your lowest-APR option.
