Your dependable reputation will make you successful in good times and bad. Don't be shy about letting prospects know who else has been delighted by your work. I was the branding facilitator for Sun Microsystem's Java Internet software in 1995, and by spreading their testimonial around I've been asked to name products for a number of other companies. Don't confuse creeping workaholism for motivation. Motivation comes from within, from loving what you do and from reaching for the brass ring.
Workaholism usually comes from outside pressures.
Motivation nourishes, and will see you through. Workaholism kills, even if it drives your bank account through the roof. Don't let dropping dead become your last agenda item. Dress for success, even if you're free to work in a bathrobe all day. Suiting up in spiffy sport clothes will keep you from crawling back into bed.
