do not confuse what i *wish* for you
with what i *expect* from you.

i wish you happiness and success in all you do.
i expect you to be true to yourself and generous with others.

i do not expect you to be happy.
i do not wish you would be generous.

do you see the difference?

peace.

simple observations

happiness (pleasure) has a chemical aspect - endorphins, etc.
thus
happiness is real

you can learn to notice your endorphins when they 'kick in'
thus
you can tell when you are 'happy'

you can note what you are doing/experiencing when your endorphins are active
thus
you can learn what 'makes you happy'

so...
accept that happiness is real
accept that you can tell when you are happy
accept that you can learn to increase your happiness

most important
accept that only you are reponsible for your own happiness
