Let Go of Sunk Costs

You are wrecking your bank account because you simply cannot let go of the past.

This is the biggest secret in accounting called differential analysis, and it saves businesses

millions. Here is the rule. If you already spent the money, it is a sunk cost.

It is literally irrelevant to your next move. Stop factoring it in.

Whether it is a lemon car or a failing product line, the only numbers that matter are

the future ones. You have to look at the difference in cost and revenue between your options

right now. Ignore the rest. Real winners know that holding onto a mistake just because

you paid for it is the fastest way to go broke.
