For me personally I try to align my motivations to get in the "being helpful" mindset. I normally don't think what's the best way I can help this particular person, its just not me, so I have to put myself there.
Where does my motivation come from, you might be asking? Well TBH, I don't always go to the same place. I grew up listening to hardcore punk music so some of that helps at times. PMA is the only way. But sometimes I listen to Jocko Willink tell me how weak I am for making excuses and I just get after it.
What helps you guys?
