Yesterday's steps you can't retrace, by slowing down or quickening pace,
changing course, or turning back - You still will be on the same old
track. The only change worthwhile you'll find, will be a change of heart
and mind - leading and directing you - on towards that lovely view.

Keep to the rules and bear your load, along the rough and rutted road,
on that wayside seat awhile - gathering strength for the second mile.
Keeping an eye on that distant height, that draws you on by day and night
- walking tall and walking straight - the better world to recreate.
