I do it, but wake up at 6am, instead of 5am for a few reasons - one, I am not a natural early bird, two, I can do the 20:20:20 between 6-7am (ie my normal life doesn’t need to start, or get interrupted, until 7am) and three - to be sustainable, this means I have to be in bed at 10pm or I get tired and cranky and stop. And I’m not prepared to have a regular earlier bedtime than 10pm, unless it’s by choice.
I started by following the 20:20:20, but now I am more lose with it. Wed and Fri I go to Beach yoga for the full hour (so I don’t do Reflect and Grow on those days), I hate Mondays with a passion, so I only do Reflect on those days - journal, have hot tea on the balcony and watch the sunrise, etc. the other days I may do the 20:20:20, or focus on a particular area to balance it out.
The main benefit I have found is that by the time the clock ticks over to 7am and the house and the rest of my life wake up and needs me, I have already feed my soul abit. Before I used to feel like I would start solving the worlds problems from the moment my feet hit the floor from bed. Now, I have a buffer in.
I also like that it is done first thing - like I am important. Before, after the day was done and everyone else - work, friends, family had all had their pound of flesh from me, I would have some time before bed for me. As I was exhausted, it was usually spent scrolling on my phone or watching Netflix etc. I don’t have a problem with these (and still do them at night!) but the difference is I’m not sitting there thinking, I should go to the gym, I should read an improving book etc, as I already have. I also find it harder to make choices like that at the end of a long day, whereas it’s easier at the start of the day (decision making fatigue hasn’t set in yet!)
So that’s my experience. Strong boundaries are key, also is working out what you are doing just doing for the sake of it, as opposed to what is actually helping you. As above, getting up at 5am (as opposed to 6am for me) would not have been successful.
