A few frequently-asked questions about how we change:

Doesn't change require personal qualities that I either have or don't have?

As a human being, you already have all the qualities you need to change, or our species would not have survived. Humans adapt. Moreover, high-potential people are often far more adaptable than most people.

Concretely, you adapt your schedules to changing events, make appointments, set dates, keep engagements, and remember to do things. These are the skills required to change, you only need employ them properly and consistently. You have the capacities and strength you need; you have only to use them in the right manner.

Won't changing self-limiting patterns require special insight or some fundamental change in my personality?

Changing self-limiting patterns requires nothing fancy. It does not depend on a burst of insight or personality change, but proceeds instead from something less glamorous and extremely commonplace. It comes from observing and developing new skills, something you have done all your life. You observe habits that have blocked your success, and then you go about replacing them with new more skilled ones. You make progress when you change what you do, not by trying to change who you are.

Aren't there some things that some people just can't change?

 Undoubtedly, there are things you cannot change, like the problem of being unable to fly by flapping your arms furiously—but more typically, what you think you cannot do is something you simply have not done previously.
