Optionality is a great ace to have in your pocket, but too many options will cause a lack of focus and certainly a lack of productive discomfort.
That uncomfortable teetering we do on the edge of failure or success will hone your focus and transform you into a powerful doer.
The feeling of "having options" or having a safe back up plan will do the opposite. So remove your options and force yourself into the uncomfortable places where work can get done.
Like Cortes did when he landed at Veracruz centuries ago, burn the boats behind you, the only way to go is forward.
