how to change the habit

You want to be simpler with the way you dress, or your habits? Just don't worry so much. Wear whatever is comfortable to you, don't worry about what anyone thinks about you. Just be happy, and don't think about it too much. Smile, and think about it this way.. My uncle told me this years ago. "If you won't remember it in five years, it doesn't matter." Focus on other parts of life that will matter in the future. I doubt anyone will remember what you're wearing!
