From a post titled The best advice I ever received by Bob Borson …
“This has everything to do with you making someone elses life easier. You manage to do that on a consistent basis, people come to rely on you and know that you can be counted on. Eventually, you move beyond being the first choice and become the only choice.
The caveat to this advice is if you can’t follow through, you need to let someone know the instant you realize it.”
