No, but here are my tips, I feel my time management skills came from being forced to navigate bad city transit as a young child alone.

1. Get a watch and look at it a lot. Time yourself doing various things, especially meditating. Soon enough you will be able to naturally ‘know’ when 15 minutes has passed. I give myself 22 minutes to get ready in the morning and I basically know what sort of delays could arise and I make time for them and adjust if I’m taking too long doing a certain thing.
2. When possible, use your voice. As in the old adage “don’t let your mouth write a check your ass can’t cash”. If you are not totally sure if you can mitigate delays, adjust the time you tell people you will be arriving and give yourself more time or warn people you may be late as soon as you know. Obviously, for certain things the arrival time is not negotiable.
3. Try not to rely on others when possible, including public transit, cars, etc. Also of course not always possible, but generally walking and biking are less prone to delays. Use map apps constantly.
