Ever hear from people that they want to be passionate about something? They want to want, but can't for some reason.

The problem is that they've become too high time preference. Their desire muscles are weak as they've been hopped up on the mental equivalent of sugary soft drinks. The most desire they can conjure up is envy at what others have. It's the laziest sort of desire there is.

Real passion requires discipline, which involves some short term suffering like frustration, boring repetition, and failure. But long term there is joy, enlightenment and skill.

Be careful what you desire and manage it accordingly.
