i find being on my phone a good way to ease the boredom of brushing while also making a checklist i try and make sure i get to check off - left back molars - left front molars - left back gums repeat on bottom - right back molars - right front molars - right back gums repeat on the bottom - front gums - front of the front teeth - back of the front teeth repeat on the bottom teeth lastly tongue note all these stages involve a front back and bottom of the individual teeth if that makes sense  this might not work for everyone but keeping a checklist on my phone so as im brushing i can tick them off as i go i understand twice a day of this is hard but try at least once i have had extensive work on my teeth and a solid threat from my dentist what what it took for me to be extra careful of my teeth  good luck
