Life is enjoyable but creating you is still saddling you with the burden of maintaining your life in a certain state so that you don't end up with suffering. Before considering taking up responsibility for any others welfare, you have to see if it's even fair to ask me to live up to the duty of maintaining my own body.
But didn't you find the trick that makes 'a duty not a burden'?
>duty
There is no duty at all unless you decide what others want/their wellbeing is your business.
