Taxonomy of Income
(Compensation vs entitlement vs gifts)


 * 1) Salary income (regular payment schedule -- once/month or once every 2 weeks)
 * 2) Freelance income, tips (no regular payment schedule, or irregular amounts)
 * 3) Reimbursements (previous expenditures getting erased)
 * 4) Interest/investment income from savings (gets bigger faster when you spend less)
 * 5) Gifts (infrequent, generally smaller amounts)
 * 6) Inheritances (once-in-a-lifetime, large sums)
 * 7) Bonuses (regular, varying amounts)
 * 8) Windfalls

Special Monies
Money with non-economic restrictions on use (social/personal/perceptual constraints)
 * Money "stained with blood", "dirty" money
 * Allowance
 * Gift money
 * non-pecuniary commodities, barter
 * special savings pot (rather spend with credit card than touch life savings)
 * College fund
