I find early morning wake-ups to be fulfilling. I get up at 4.45am daily, and there is something about being up then that just feels... different. For me it is partly because by the time 9am rolls around I feel a sense of accomplishment and readiness for the day.
It certainly wasn't always like this. It's taken 5 years to get to this point, during which I experimented with brutal 4am wake ups and getting up at what is probably my natural body wake up time of 7am.
I'm all for relevance so my point is this; waking up early can bring a sense of silence and solitude. These help with focus, and that focus is so very helpful for getting things done. It also brings a useful sense of inner calm to face the day. Such is my experience at least.
