Was Einstein wise??? Einstein’s Definition Albert Einstein once said “The definition of insanity is doing the same thing over and over again and expecting different results”. Think about this quote for a second and ask yourself Taco, does this quote apply to the way you run your love life? Do you want to admit what you are doing is absolute insanity? Following her still, trying to convince others you are right, controlling those around you to believe what your reality is. Freakin' stop already.
