Hum, usually my best minute is after something. I'm not one to enjoy the present (since the present is so short) but always to think of the future and look at the past and since the future is uncertain, the best thing is to recall something I've made, either a long time ago or just before, like sharing a good kiss with a girlfriend and feeling like everything couldn't be better, waking up after a good nap, going to rest after a day full of work, enjoy the sun in my face and praise life, finishing eating...Some last for more than a minute, others don't!
PS: I forgot to say - that minute after the plane landed and there's no more risk of crashing! Oh, what joy!
