Give yourself time and space to get things done
I mentioned above that HSPs don’t do well with a packed schedule. I’ve managed to structure my work life so that I work afternoon/evening shifts the days I’m at the medical clinic. This way I’m able to get out of bed without an alarm, eat a calm unrushed breakfast and putter around before getting down to business. The calm this gives me carries through my whole day. Another strategy for those who work in the morning might be getting up extra early (after 8 hours sleep, of course) to enjoy the quiet before the rest of the household wakes up.
