Little things are what make your life have sense, even if you think it's a nonsense.
It's like, how can my life be this way? and it's just because you have plenty of things you don't realise they're there, waiting for you and changing your life for moments.
Maybe one day you take away the pillars that holds your life and everything collapses, but removing only a brick, the structure crumbles too.
So just keep on walking and adding those little things that make you feel better everyday, just one simple smile, one look, one hand, one moment.
