LAW OF AVOIDANCE
The more something threatens to change how you view yourself, how successful/unsuccessful you believe yourself to be, how well you see yourself living up to your values, the more you will avoid ever getting around to doing it.
There's a certain comfort that comes with knowing how you fit in the world. Anything that shakes up that comfort - even if it could potentially make your life better - is inherently scary.
The law applies to both good and bad things in life. Making millions could threaten your identity just as much as losing all your money; becoming a famous rock star could threaten your identity just as much as losing your job.
