The most confusing transaction in any ledger will be your equity account---
because starting balances can't come out of nowhere.

When you first start your ledger, you will likely already have money
in some of your accounts.  Let's say there's $100 in your checking
account; then add a transaction to your ledger to reflect this amount.
Where will money come from?  The answer: your equity.

But what is equity?  You may have heard of equity when people talked
about house mortgages, as ``the part of the house that you own''.
Basically, equity is like the value of something.  If you own a car
worth $5000, then you have $5000 in equity in that car.  In order to
turn that car (a commodity) into a cash flow, or a credit to your bank
account, you will have to debit the equity by selling it.

When you start a ledger, you are probably already worth something.
Your net worth is your current equity.  By transferring the money in
the ledger from your equity to your bank accounts, you are crediting
the ledger account based on your prior equity.  That is why, when you
look at the balance report, you will see a large negative number for
Equity that never changes: Because that is what you were worth (what
you debited from yourself in order to start the ledger) before the
money started moving around.  If the total positive value of your
assets is greater than the absolute value of your starting equity, it
means you are making money.

Clear as mud?  Keep thinking about it.  Until you figure it out, put
@samp{-Equity} at the end of your balance command, to remove the
confusing figure from the total.
