You May Be Conservative, Cautious and 'Practical"

So you look both ways before you cross the street,
And then you look both ways again,
And then you look both ways again.
But what is that doing besides making you late?
And now I look both ways more than once, but only from habit.
I've seen how your fears limit you,
And I've seen how your fears limit me.
I've seen your so-called practicality turn into complete irrationality.
And if you're too cautious, you're just wasting time.
You may be conservative, cautious and practical,
But I am not.
