Re-learn ..... often!

The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn
Alvin Toffler

Businesses too have to be flexible. Expect - and deal with - change. Have your staff ready for change by keeping them updated about your products, your business environment, your customers. If they can't cope, its because you didn't prepare them well enough.
