For me writing help in the form of :

Stress buster : Whenever I'm too much stressed or having a pressure in life be it work, relationship or anything for that matter I try to jot down everything and almost anything that comes to my mind in the form of rhythmic poetries.

Memorize : I have been learning things throughout my teenage by writing it down when it comes to academics and believe you in me its so much easier to remember things which you have written than you have heard or read.
