You are one decision away from changing everything.
Accepting that one offer.
Meeting that one key person.
Making that one big move.
Burn the boats is a call in which you leave no other option for yourself other than the decision you have committed to. In 1519, Captain Hernán Cortés landed in Veracruz to begin his great conquest. Upon arriving, he reportedly gave an order to his men to burn the ships in which they arrived in. There was no return.
Make that one decision then burn the boats to any other alternative or back door.
