This is something I wish I saw more talked about: how to get better at estimates. I wish more people dedicated time to reviewing their projection & mindset at the time, then look at the task timeline, then write down what caused it to go off schedule. Sometimes it's an environment change. Are these consistent? Can they be modeled statistically? Often, it's an inaccurate belief in the work to be done. Was it lack of requirements, that had to be expanded? Etc. When I work in development, I spent up to 20% of my time on "overhead" tasks. These are of the estimate review type, not meetings. It's something a great manager will do without wasting his team's time, but as an independent, I spend a lot of time doing it myself, and it's amazing how much it helps to dedicate time and write things down.
