fist vs tact

I've dwelt long on the past and I just can't take it anymore
I struggle in vain at last, I've managed to board
Up the windows and lock the door

Persist to resist, fight back
Not with a fist, with tact
Ideas in action, with passion
Passion commitment, dedication

When all is said and done, our time is spent
And we've had our fun
Have you taken the time to think about your life
And what it means to know eternity?

I've dwelt long on the past and I just can't take it anymore
I struggle in vain at last, I've managed to board
Up the windows and lock the door
