Spiritually

Spirituality means to offer something to God. It's the acting out of an idea;

a deep idea.

The idea of work itself.

Work itself is sacrifice.

In order to get something you need and want in the future, you gave to let go of something of value in the present; and that's the discovery of the future

We can alter our our actions in the present so the future may change-

The discovery of possibility itself!
