Cover art for Getting Wise lyrics by Yves Klein Blue

I had no idea what "find our feet" meant. So I asked my friend, and apparently it's an idiom that means becoming used to a new situation. So I suppose that this song is saying that being wise means you have to always be willing to try new things. So my interpretation would be "A lot of people don't know what they want in life because they haven't tried enough things to discover what makes them happy."
