Dobbersky, you shouldn't limit yourself. Iv'e learned useless techniques at least from my perspective and changed it to the way I believe it'll work for me. I always tell my students that if they think something doesn't work or they don't agree with to tell me so I can understand their point of view, and who knows, maybe i'll learn something new.
Everything in life has things that not all agree with but sometimes has to be done in order for the individual/s to develop the foundation needed to further progress.
