Very good post, i also think that when people are not happy, its because there are a lot of small irritating things that they all put up with because they feel that they have to and they think its just another problem so what, kinda like thinking when it rains im already wet so what does it matter if i get soaked even more, as i am typing this im sat itching my arm from the overgrown
prickly bushes that i ride past on my bike on the way home, and i did the same yesterday, so tomorrow i will take with me a pair of scissors and stop for a minute to cut the overhanging ones back and that will be one less thing to be unhappy about :)
