For me it was three things:
I was already working from home most of the time, but it becoming full time provided more flexibility.
Increasingly over time, I reduced my actual working hours (being lucky enough to do so) without a pay cut. I know I’m not getting pay rises anytime soon. So it seemed appropriate that I spend lesser time working.
I started exercising regularly, and have included at least one yoga session everyday towards the end of the day. I practice for 30-45 minutes by watching someone’s instructions (either an app or video). I don’t know when I’ll drop the regular practice, hopefully not soon. Next on my list is to make meditation a daily practice.
If there’s one piece of advice I could give people about work, it is that there’s always tomorrow and next week and next month and next year to do it. There are many other things that could matter more in life.
