So it's been established that self acceptance is about taking inventory of yourself and putting a check mark beside every one. Both the good and the bad.
Firstly, this isn't a one night show. Taking this inventory takes a while, and furthermore it may take more time to be comfortable putting a check mark along side it. This is a long process. For some, it takes days, others perhaps years. Some finish life without ever accepting themselves. Vanity and shame is being called here. (shame is an evaluation of the person. guilt is the evaluation of the act. there's a difference)
One of the first things to do is to stop the value comparisons. Status comparisons are different. A status comparison is checking the gas meter. The value comparison is saying that a low gas reading makes the car worse than at least 50% of all the other cars in the road.
Meditation and logical reasoning helps here.
After a while, there's a time when one's world view changes for the more optimistic or the more opportunistic. Decisions are made more quickly because this self acceptance has provided a personal definition of oneself that was conducted by oneself.
This then just describes what a person is, and this is only half the story. The next portion asks what does this person wish to become.
What the person is, and what the person wants to become both make up the true picture. If a piece is missing, an unhealthy mindset or world view may develop.
Viktor Frankl and Albert Ellis comes to mind. Frankl's "Man's Search for Meaning" is a great book on this thread of ideas. And from the therapy side, Ellis' REBT therapy is a great tool to help get through the inventory.
REBt works on the ABC principle.
A = activating events
B = Beliefs about A
C = Consequences
Then, one tries to change the beliefs in order to alter the consequences.
So it starts with the self acceptance/inventory and then progresses into self confidence and then life goals. From knowing where you stand, to knowing where you're headed.
