My favorite is #2 Spending time with the wrong people. Our surrounding plays a big part in our personal growth, whether we want to admit it or not. Sometimes we need to let go of those so-called "friend." It doesn't have to be always easy but we need to prioritize our time and energy. I certainly limited my surrounding in the past year which brought me more time to realize my goals and also to spend time with people who actually matter in my life.
