When you make a mistake, the first time, and it costs you (and it will cost you something), learn from it and call it (the cost) tuition.
If you make the same mistake, and it costs you (and it always does, in some way), it’s a tax (and the mistake (i.e. lesson) will keep showing up until you learn it).
Tuition is an investment, and makes you more. A tax is a cost, and a drain.
