Musing when I should be focused

Take action.  Take it where?  Why is that the phrase?  What are you taking?  I’m doing an action.  I’m performing an action.  I’m not taking anything when I act.  Unless I’m taking something from you?  If I take an action, am I preventing you from taking it?  In some cases, sure.  In others, most, not in the least.  So why is that the phrase?  Google is not so helpful this time.
