Don’t put yourself down and elevate others around you. It’s great to compliment other people, but it shouldn’t be phrased like “Oh, yeah, look at Silvia, she really knows how to make a beautiful garden. I can’t do anything like that.” It should just be “Oh yeah, Silvia knows how to make a beautiful garden.” Period. Nothing more. Nothing about what you feel you can’t do because there are other things you can do very well, that I bet Silvia can’t do.
Feel good about your talents. They belong to you. And if you want to plant a beautiful garden and feel you just can’t do it then ask Silvia to help you, or hire a landscaper. That will free up your time to be the best you can be.
