Overview
A very small detail may derail some of your big plans today. But this doesn't mean that you should cast a paranoid eye on every little thing that you encounter throughout the course of the day (that'd be pretty exhausting!). Rather, just be aware that this slipup may occur. Even on the best of days, you can't make everything perfect, so don't waste your time trying to. Just stay limber, and be ready with a backup plan in case things do go awry somehow.
