Investigated it,not for me,too passive,nihilistic and selfish. (excuse my french.) Even as a tool i find it faulty because of its theoretical background asuumptions . (impermanaence et al.) However,i know it appeals to a lot of folks,so each to their own.
I'm not trying to convert you , but it is not nihilistic - The Buddha taught the Middle way between extinction and a permanent soul, and some of the main teachings - depending upon which school - relate to developing compassion. Selfishness is also negated with teachings on non-self, emptiness and compassion. Anyway - no worries.
