One of the keys to reaching your goals is to eliminate any escape routes. It is tempting to retreat to safety and comfort when challenges and difficulties arise. To avoid turning around and abandoning your goals, you must make going forward more compelling than going back.
When striving towards a goal, you must focus on what you want to obtain, and avoid the impulse to go back to what you know, and to what is comfortable. When Spanish Conquistador Hernán Cortés landed in Mexico, one of his first orders to his men was to burn the ships. Cortés was committed to his mission and did not want to allow himself or his men the option of going back to Spain. By removing this option, Cortés and his men were forced to focus on how they could make the mission successful.
Eliminating an escape route creates a compelling reason to focus on the goal and to keep moving forward. However, it is important to keep in mind that although Cortés had his men burn the ships, he did not have them burn the food and supplies. Cutting off an escape route to increase motivation and create the desire to press on where you might otherwise give up, is totally different from throwing caution to the wind and taking undue risks. Reaching your goals still requires prudent planning and managing. All goals contain a certain degree of risk, but it is not necessary to create undue risk and stress by not properly planning and thus lacking the necessary tools and supplies to achieve your goal.
Before you decide to burn your ships, make sure you have the supplies and tools necessary to achieve the goal. Something like quitting your job might sound like a good way to close the escape route, but it might also be a fast way to bankruptcy if you do not have resources to carry you through. Having sufficient savings in your account or having a journey job (a job that is a stepping stone to what you really want) allows you to take the risk of leaving your current job without creating undue risk.
Close off the escape routes and make sure that you have a compelling reason to move forward. However, at the same time, make sure that you plan for the risk and have the tools, supplies, and resources you need to achieve your goals. You cannot eliminate risk but you can plan for it. Do not just jump in without thinking through the process and having a solid plan for moving forward.
