That's how I thought the fear of embarrassment turns into motivation too, but that is not real motivation as it doesn't come from within but from the outside, fearing of disappointing others or fearing personal embarrassment. That may work to keep one going but the reality is that things change, priorities change, motivation fades for good reasons. It is probably better to not announce anything until you've started off and made some progress and realized that you're on a good path.
