Or watch the things you gave your life to broken, And stoop and build 'em up with wornout tools;

Sometimes other people will break your toys. Rarely is it malicious.
However it is always done in a way you never would have allowed. The
reality is you would have broken your toy in a different way.

Relationships, contracts, contacts and companies all are at risk.
Sometimes you will need to play cleanup. Other times you will rebuild.
It can become wearying to constantly build and rebuild infrastructure.
But the organization always needs it.

Be prepared to go over ground again. It's all part of the game.
