  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times.

I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: 6 months ago
