How often are you apologizing for yourself?
How often do you give a disclaimer when you share something you created? It may be work, a meal, a painting, your hairstyle. Do you give a disclaimer with it? "It's not perfect, but…" or, "I didn't have enough time to get it exactly right…" or, "I'm not a real artist, it's just a hobby."
Businesses use this to get themselves off the hook if their product or service doesn't work as advertised. "Results not typical," or, "If you aren't satisfied we'll give you your money back." How about boldly and unapologetically standing behind what you offer? This would require a) believing in yourself and b) believing in what you're offering.
When you discount yourself the rest of the world will too. Value yourself enough to stop apologizing for being you. Don't use disclaimers to hide your insecurities. Sharing parts of yourself is an act of courage and vulnerability – and these aren't to be confused with weakness.
