The work done on an object

is equal to the energy gained 

by the object.

Work/Energy Theorem

The thought that energizes you

The person who motivates you

The dream that keeps you going

Energy

Give it...get it

and then

keep it going

and that's poetiquejustis

For this I toil, struggling with all His energy that He powerfully works within me. 
Colossians 1:29
