Addressing one of your concerns head-on, as we just discussed, is one way to deal with this, but there are going to be situations where that’s simply not possible. Instead, what if you set aside a specific time in your schedule to move these worries and obligations to the forefront of your mind? Simply saying, “I’ll worry about that later” isn’t likely to keep that worry from creeping back 20 minutes from now. But saying, “I’ll worry about that at 4:15” very well might.
