The jacket

Every step you take,
every decision you make
closes a door, blocks a path,
it's obvious if you do the math.

The freedoms you have will erode,
straightjacketing you down the road.
As time passes by you'll think more
of what you don't have, but had plenty before.

The hourglass runs out of sand,
look closer, make note of the trend.
The choices you still have today...
Tomorrow - they're going away.

And then life wants to give you a high-five!
