Interesting Quote...Again

I watch TV9 Semanis Kurma..and this quote interest me...it simple forgive me if my translation not good....

'remember 2 things and forget 2 things, remember all the bad things that we done to others and remember good things that others done to us. Forget good things that we done to others and forget bad things that others done to us'

The reasons that we need to remember the two things so that we will appreciated the good things and not repeating the bad things....

The reasons that we need to forget 2 things so that we can fell calm to ourselves when we forget good things we done to others that showed that we do it for Allah s.w.t not to gain something,the reasons we forget bad things other do to us is to get us far away from hatred and anger as this 2 attitude is the attitude of devils...
