Life is a mirror and will reflect back to the thinker what he thinks into it.
Ernest Holmes

We all want progress, but if you're on the wrong road, progress means doing an about-turn and walking back to the right road; in that case, the man who turns back soonest is the most progressive.
C. S. Lewis

One looks back with appreciation to the brilliant teachers, but with gratitude to those who touched our human feelings. The curriculum is so much necessary raw material, but warmth is the vital element for the growing plant and for the soul of the child.
Carl Jung

Just cause you got the monkey off your back doesn't mean the circus has left town.
George Carlin

Don't look back. Something might be gaining on you.
Satchel Paige

Queen - Going Back
Words and music by Gerry Goffin and Carole King

I think I'm going back
To the things I learnt so well in my youth
I think I'm returning to
Those days when I was young enough to know the truth
Now there are no games
To only pass the time
No more colouring books
No Christmas bells to chime
But thinking young and growing older is no sin
And I can't play the game of life to win
I can recall a time
When I wasn't ashamed to reach out to a friend
And now I think I've got
A lot more than just my toys to lend
Now there's more to do
Than watch my sailboat glide
And every day can be
My magic carpet ride
And I can play hide and seek with my fears
And live my days instead of counting my years
Then everyone debates
The true reality
I'd rather see the world
The way it used to be
A little bit of freedom's all we lack
So catch me if you can
I'm going back
