Focus, in general, and not just during work

The idea of scheduling each minute of my work day is one of the tactics to improve focus and become good at work. Because, when I used to do that, I would wonder what to do after the work day is over.
- The idea of going deep only during scheduled times was also limiting because I wasn’t focusing at other times. For e.g., during shallow blocks, I was still haphazard in checking emails or Slack.
The more important thing is to improve my focus or concentration in general. (Is that called mindfulness?) Some ideas are:
- Do exactly one thing at a time. So, even if I pick up my phone or am at my laptop, I should know upfront what am I going to do, and then just do that.
  - Unwavering focus.
- Quick checking email or Slack is bad because it leads to attention residue.
- When situation permits, I should schedule time to do deep work. I can plan my day one day before or along the way, either might be okay.
- Boredom is good but I also don’t have to overdo it. 1-2 times a day is okay.
Wake up on time and get to work quickly. Don’t waste time during the work day.
It may be obvious but technology itself isn’t bad but how I use it.
Mind wanders by default and that’s a good thing. And it takes practice to make it focus, i.e. stick to the task at hand for a long period of time.
- There are limits to how much I can be in a focused state of mind - can’t be the whole day. So I am wondering if there is a way to track focus time per day.
- I can go to this mental gym any time during the day: just concentrate on breathing and bring back the mind to it if it wanders off.
