Brute force stopping of certain thoughts and impulses in the mind is a very important technique, because the human mind is vast and the human conscience can have a plethora of analysis to perform, curiosity to satiate, planning to do.
There are a lot many unresolved issues that pop up and crop up from time to time that have the potential to derail focus, derail one from the planned course of action and thus lead to inefficiency in the act of achieving progress in ones journey.
Without brute force, one may be tempted to sway with the wind and go here and go there mentally and hence alter the original path and hence halt/dissipate progress, due to lower compounding.
Hence, use brute force to increase efficiency in life, aptly.
