I'm one of those people who has a hard time learning how to accept a compliment. It comes from years of self-doubt and an inability to believe in my own worth. One of the thoughts that has made it easier for me to accept compliments, or to at least acknowledge the fact that one has been paid, is consideration for the person paying the compliment.
If someone has gone to the effort to offer you their sincere congratulations or praise, than the least you can do is graciously accept that compliment. What amazes me is how many people, who are not afflicted with my past, will seek to brush off compliments with vague generalizations or trite denials.
False modesty is in some ways far more egotistical than the most aggressive self-promotion. In some ways, dismissing someone else's opinion is the same as saying "What do you know?" When you think about it, there is actually more humility in accepting a compliment graciously than in pretending not to deserve it.
There's a big difference between humility and false modesty, with the former implying a sense of dignity and the latter simply self-serving. Sometimes I fear that the world we live in, or our society, which is the world I'm most familiar with, knows far too little about humility and far too much about the pride that goes with false modesty.
To me humility and humbleness indicate an ability to show gratitude for the praise you are receiving and the ability you have been gifted with. Sure you've had to work hard to refine your skills to the point where you receive praise, but without some core ability that you were born with, unique to you, that hard work would be for nothing.
The ability to interpret inspiration as writing, whether fiction, non-fiction, or poetry, is a gift whose origin I'm often at a loss to explain, but one I'm eternally grateful for. I only need look at the void left in my day when I'm unable to write, for whatever reason, to know how bleak and desperate my world would be without it.
