Is that good?

Is that good to forget things easily? Sometimes i cant recall back our memories.. i only remember some of it (sweet moment) but i never remember the moment that i have done wrong. Maybe there is something wrong with my personality and attitude.. Maybe kept hiding too much feelings or pressure. When I pissed out, i totally cant control myself nor calm down.. Pityful. Really hope there is someone who is understand me so that i can understand i myself...
