you are sending the message to your subconscious mind that it's ok to quit.

If you don't burn those ships, you are sending the message to your subconscious mind that it's ok to quit. And when the going gets tough, as it inevitably does for any worthwhile goal, you will quit. If you really want to achieve your goals, then you've got to burn those ships to the ground, and scatter the ashes. If you're thinking that the average person won't do this, you're right -- that's why they're average.
