Bullshit – Meaningful, inspiring ideas that that seem to promise something, but that something can never be fulfilled through any practical action.

Chickenshit – Practical activity that seems like it ought to serve some meaningful purpose, but in reality is pointless busyness.

Bullshit is meaning without practice. Chickenshit is practice without meaning.

If you can bring together meaning and practice, so your meaning is a positive something that can be realized and your practical actions are a means to a meaningful end then you are The Shit.
