Motivation is the fire in your engine. Sales is the transfer of motivation from one person to another. Without that fire, you can't make yourself move in any direction - let alone help someone else get moving. If you're not getting your motivation from somewhere else, that's called vision. If you can sell that vision effectively, they will call you a leader. If you lead well, you will succeed. But it all comes back to the source of your motivation.

12. Phase 1: INPUT
The input routine reads formatted data records.
Data for each observation consist of
Item responses of individual examinees comprise one character for
each of n items.
The answer key, not-presented, and omit codes are read in exactly
the same format as the observations.
For aggregate-level data, the "responses" consist of number of
attempts and number correct for each item.
If data are for the aggregate-level model, vectors of numbers of
attempts and correct responses to the items are read in decimal
format.
