well, most important things in life just demands friction. period. no long term satisfaction can ever happen following a 'frictionless' process. no true love or friendship take place through a 'frictionless' environment.

as everything else, I found out growing up that it's all a matter of 'balance'. too much friction can be as painful as not enough. and I realise now how bad humans tend to be at finding out 'balance'. this might be a skill we could all train for though. idk.
