In the Effortless post, the challenge of accepting compliments was discussed. This skill is very important to understand in the effort to be feminine.

This post from Entrepreneur titled, "How to Receive a Compliment Without Being Awkward About it" discusses the negative implications of poorly receiving a compliment:

Though you may feel as if you’re responding appropriately, it only undermines the compliment or insults the giver. When you devalue a compliment, you can send the message that you have a low self-esteem, aren’t confident in your work or don’t respect the opinion of the person who gave you the praise.

Low self-esteem, lack of confidence, and disrespect aren't desirable traits.

Here is another good post about graciously accepting compliments from The Art of Manliness (graciousness is fitting for both sexes, obviously.)

The first step in quitting the faux modesty of the compliment deflection routine is to realize that fully accepting compliments does not make you conceited. You didn’t come up with the praise yourself, someone else did! You’re just confirming another person’s assessment, and again, it’s more polite to accept and appreciate their judgment rather than to contradict it.

Second, it’s okay to let yourself feel proud of something you did well. A little pride need not involve an inflated sense of your accomplishments or worthy qualities – just an honest assessment of what you did. It’s quite possible to be modest, while still being grateful and gracious.

A lot of the content in the posts I've found seem recycled, but here's an interesting bit from a post titled "Affirmation from Others: Are You Listening? that I found interesting:

Even if you suspect that the person’s motives aren’t genuine – if they really are lying, or trying to butter you up – who cares? That’s their deal. You can still accept the compliment. You can still choose to see it as genuine! Accepting the compliment may very well disarm their ulterior motive – and besides, you don’t have to be party to that motive. Right now, feel good about the words said to you!

Something else that I think goes a long way in becoming more comfortable with receiving compliments, or at least more motivated to do a graceful job of it, is more readily giving compliments to others when the situation is appropriate. Observe people's reactions when you give them compliments... how do those reactions make you feel as the person gifting kind words of affirmation? What reactions do you admire that you can adopt yourself? What kinds of compliments land better on different individuals?
