Happiness is like million microscopic, small, big points on the map of your life. Close your eyes right now and you will find one small source of happiness even when you are facing terrible crap right this minute. TRY IT.
If you are breathing, it is impossible to not find even one. Like, you just had a great breakfast or the shower was great, or the flower you saw was pretty, or your car runs just fine today, or you have not been to the doctor in months, or you ate the candy and it was delicious, or your parents called to say hello, or your friend took you out for coffee.
You get it? Small things. They are not small really. If you know what I mean!
