Does this sound like the set of challenges you might be facing?
- I pack my day back-to-back with no gaps, so the moment one thing runs long or something unexpected pops up the whole rest of the schedule collapses like dominoes and I’m behind on everything by noon.
- I plan my day down to the minute assuming everything goes perfectly, and then the first delay or surprise topples the whole thing like dominoes
- I plan every day packed end to end with no gaps, so the first thing that runs long knocks over everything after it like dominoes
- I tend to figure out my plan the same morning I’m supposed to start, in a rush to just get going
- Every hour of my day and every dollar of my budget is already spoken for, so the moment one small thing goes sideways the whole thing topples
