Starting routines is hard.
The only way to start a routine is to do it now. You might tell yourself it’d be best to wait until things are little slower. Maybe you have an upcoming trip or the holidays are around the corner.
You want to wait until the time is perfect. I’m sorry to burst your bubble, the time will never be perfect.
You need to start now. Today is the second best time to start, of course after yesterday. ;)
