Which I would counter with another short phrase:

The market can stay irrational longer than you can stay solvent. Your competitors earned some money and will gain interest on it, if they are smart.

[TeMPOraL]

And because they saved the money that you spent on building a good product, they now have more money to spend on marketing than you.

Staying solvent is fine if one is profitable.

The "market" the quote relates to is the stock market. Very different than selling products to be used.

If you invested in the product itself (instead of marketing), that can gain you something as well in the long term.
