I've already given you the tip about setting alarms for every task you complete regarding your business, now it's time to reveal my next tip.
Writing everything down.
If you're having a hard time following a routine, then it's time to write it down. I highly recommend getting yourself a planner. Yes, we have calendars in our smartphones, but writing things down and seeing them in our handwriting helps with retaining the information.
Using a planner has kept me from going insane. LOL
At one point, I even had to schedule "eat lunch" into my planner so I wouldn't forget.
There are tedious things that we overlook when we get caught up in working on our business. Having a friendly reminder is a great way to stay on track.
It also helps for when your routine does get out of the norm due to special events like a friend's birthday or a doctor's appointment.
Keeping a planner handy is also going to help keep you accountable for the tasks you have to complete. It's like physical proof of what you need to get done.
I use a weekly planner. It starts in July and ends in June. If you'd like, you can get a dry erase calendar, or just use the app on your phone. Just remember to turn your notifications ON.
