Everything is temporary, emotions, thoughts, people, things and scenery.
Reminding yourself of this can be effective way to increase your gratitude for the present moment.

Segala sesuatu di dunia ini bersifat sementara, emosi, pikiran, orang, benda, dan pemandangan. Ingatkan diri anda tentang ini dan syukuri apa yang anda miliki saat ini.
