Beware sales pitches.

If someone is getting a commission to sell you something, chances are they’re not thinking of you.

They’re thinking of themselves.

The safest rule is to not buy anything that is pitched to you.

When you buy something, it should be because you’ve decided for yourself that you need it.

Any other reason is bad for you, and your wallet.

Ignore advertisements and salesmen.

If he’s selling, don’t buy.

(PS: as an entrepreneur, your first job is to be a salesman. Remember to be thinking of how you’re helping the customer, not how you’re helping yourself.)
