Caring about others will ultimately also be about caring for yourself.
If you want the people that love you and are close to you to flourish and thrive, to be happy,
it logically follows, that they need to be sure you are OK, actually good and genuinely doing great.
So, the argument goes, if you need external motivation for things you need to do - like work, study, thesis, laundry, whatever,
then know that
'when you do better, we do better'. (SW)
