Don't know what i'm doing

I used to know where I was going
I used to feel like I was sure
I knew the way the tide was flowing
But I don't know what I'm doing anymore
 
I used to walk without a worry
But now I feel so insecure
I used to travel with no hurry
But I don't know what I'm doing anymore
 
'Cause the world is ever-changing all around me
And time is moving faster than before
The walls are getting higher that now surround me
And I don't know what I'm doing anymore
 
I used to talk with such precision
There was no doubt, there was no flaw
I used to feel no indecision
But I don't know what I'm doing anymore
 
I never thought beyond the present
I never looked beyond my door
My life it always felt so pleasant
But I don't know what I'm doing anymore
 
'Cause the world is ever-changing all around me
And time is moving faster than before
The walls are getting higher that now surround me
And I don't know what I'm doing anymore
