Bootstrapping alludes to the legend off Baron Münchhausen, who was able to lift himself out of a swamp by pulling himself up by his own hair. In later versions of the tales he was used his own boot straps to pull himself out of the sea which gave rise to the term bootstrapping.
The phrase “Pull yourself up by your bootstraps” means simply to improve your situation by your own efforts.
NLP provides an ideal methodology for bootstrapping. By helping you to understand how your mind works you can make massive changes in your situation…!
