I take an extremely methodical approach to most things I do in life and my daily routine is no exception.
My usual morning starts at 5am. While I don't often drift from this wake-up time, I do give myself a pass if the night before was a late one or if I woke up many times during night.
I've learnt that sleep is an asset you can never "catch up on", and I consider it extremely important in setting up the day for success - whatever success ends up being that day.
After waking up, I spend 20 minutes meditating. This hasn't always been the case but I've found it remarkably efficient at forcing you to slow down and see things as they are and not what you perceive them to be in the moment. Depending on the work and challenges I've got going, I write some morning pages to get my monkey mind trapped in ink. This has been super effective for working through a range issues and it's so simple!
Once I've got myself in the right headspace for the day, I will have some breakfast and duck out to my favourite coffee shop.
Depending on my mood, I will either spend an hour or so working on some open source project or reading. I've found it quite beneficial to switch this up as I don't consistently feel like either but do enjoy both.
The actual work day does tend to start a bit earlier than others at HQ despite being in the same timezone. Thanks to our asynchronous communication style, this means mornings are generally periods of long, uninterrupted work for me.
This does vary if I'm on call or working with teams in other time zones, where the morning is our only overlap.
I'll work until I feel hungry, which generally happens at 11 or 11:30 - I'll then make sure I get outside and grab a bite to eat. If I've made myself some lunch at home, I'll go out to enjoy it either in our yard or at one of the great local viewpoints. Sometimes I'll even get a sneaky skate in before returning to work.
Sometime between 4 and 5, I'll hit that mental wall and will call it a day. I'm very wary of working a lot of hours.
When I first went remote, my wife was an awesome alarm clock to remind me to get out and finish up the day. These days, I don't need the poking, since I am far more in tune with when I need to take a break.
