Don't fall in love with your failed products or else they will drag you down with them.

When your product is a failure, you need to let it go.

I saw a show with monkeys who were captured by throwing food inside a tight hole, and they would get stuck after trying to grab that food and closed their fist.

The closed fist holding the food would be too big to fit through the hole!

So, don't be like the monkeys and let go of your products, as the consequences may be devastating if you hold on too long
