If I've learned anything in the past year it is this:
The self doubts I have about what I can accomplish in a day are fake.
An abundance of free time has been given back to me from what used to be spent walking to the coffee machine, attending meetings, commuting to the office, etc. The small, trivial things spent in between the time where actual work gets done have been converted to free time.
What have I done with this free time? In March and April it was self loathing and guilt.
In May and onwards it was intense introspection about what is truly important and what is truly blocking me from pursuing the things I think are important. (Hint: it wasn't time)
As you rightly put,
there are things to be done!
Carpe diem!
