To "accept" a thing is, essentially, to receive it willingly. One's body is not a thing that can be accepted or rejected, because one has always had it; one cannot receive it.
There are, however, things that it is possible to accept. For instance, I wrote, it's possible to "accept" a discomfort (meaning to endure it willingly), or to "accept" a proposition (meaning to believe and assent to it willingly).
So here are some propositions I urge my readers to accept, instead of wondering whether they should "accept" their own selves:
(1) Permanent personal change would require you to accept discomfort.
(2) Today, there is a limit to how much discomfort you can accept and for how long.
(3) With practice, you can increase that limit.
(4) That is: Accepting discomfort really can change you. For the better. Immediately.
Readers: Do you accept these propositions?
