I recently got laid off, and even after seven years it is hard work. Definitely not my field of choice but meh, I suck at interviews and it's hard to find a decent job here in California without years of experience or a bachelors. So now I'm going back into shopping after a season of working a labor job. Yesterday I did four. I did three in a route, went home and did all of the reports. I then went out to do my last one for the day, a dinner shop. At the restaurant for an hour, got home a little after 8, it took almost two hours to do the report. Wrapped up my day at 10:30.
To sum up my Saturday: 4 shops, 12 hours, $43 profit, two toys for my kid, free lunch, and free dinner.
Just pace yourself. And remember, calendars are your friend. Soon as you have something, put it on. If you're requesting something, take a moment to look at your calendar to make sure you can handle it.
Looking at my week, I have 10 shops to do on top of other plans and commitments. Does my schedule look packed and over booked? Absolutely. Do I feel like I'm going to be overwhelmed? Not at all, because I took time to plan it out.
