Once pay arrangements became simpler, leaders could focus their efforts on more useful activities.

But all are closely related to useful activities, and so can be overdeterred.

Takeovers were a small and useful activity in the mid-1970's.

In Paris you had special companies charged with carrying on activities useful to your counter-revolutionary plans.

A bit of useful activity would be good for you.

From then on there were no more odd jobs or useful activities.

Small organisations that carry out very useful activities at local and regional level need special help to draw up applications.

If they do, so be it, they will have less to spend on more useful activities.

'When are you going to be sensible and turn your mind to useful activity?'

In that case I promise you to turn my back on the past and force myself into useful activity.
