You need to be pulling your weight

I've got the weight of the world on my shoulders

I've got pain in my shoulders

He's a pain in the ass

Do you have any pain relief medicine

It took great pains to get here

That's a great idea

Great minds think alike

The mind is a terrible thing to waste

Waste not want not

I'm wasted 

You're wasting away

Stop wasting my time

Time is of the essence

Only time will tell

Does anyone really know what time it is?

I got no time for that

Time to face the music

Too much time on my hands

Time to make the doughnuts

Just in the nick of time

Time is on my side

Always late never on time

Now is the time

You've made your bed, now lie in it
