Stay in your team

A man builds a team for many years,
And wades through turbulent waters,
Never having the joy of victory,
One day victory smiles at the tunnel end;
And shines its way forward;
But the man abandons the team
And starts a brand new team;
With no idea what’s in store ahead;
What do you say he’s done?
A wise thing or unwise thing?
Be wise and stay in your team;
The time to reap is at the corner.
