I would love to be able to see my monthly income and outcome as a series of water tanks / pipes / taps and buckets Day by day you can add or take away money from any designated taps At some point during the month your payday bucket tops up the main water tank Using valves set to an amount designated by you; the income is siphoned off into seperate water tanks At the designated time the money is drained away from those tanks ready for use next month
