In an effort to energize you to take action, let me synthesize all of the advice into two, simple words: Become Irreplaceable.
Think about it – how much more secure would your revenue base be if your customers/clients felt you were irreplaceable; if you were absolutely necessary? How much faster would you grow, and how much more profitable would that growth be?
Ask yourself what would your customers/clients have to feel to think about you as being indispensable? Now, what’s the first action you have to take to get them feeling that way?
Go do it.
