No one will achieve happiness until you release the illusion of control over other, ex an appletree, you can not make the tree to blossom went it suites you or make it bear fruit before its time. There are things you can control, you can control when the fruit will fall and you can control where to plant the seed, but what ever you do, the seed will grow to be an apple tree.. you can hope for an orange tree or a pear tree but it will still become an apple tree. The apple tree can saturate your own hunger, but if you want to share, it can feed many more if you are willing to guide it, to belive in it. What I am trying to say is that what you do, you can not change people for how you want them to be, but if you believe in them, they will come to think not only about themself but also provide the same hope for others that them self has been given.
