So in short list format, just sharing some methods I employ, sans digressions:
0. Awareness. Took way too long for me to reach it.
1. What is mentioned in the article: prioritisation! That needs to lead to routine. Hard work this, but most important, as I have to be able to engage auto-pilot for "non-interesting" tasks.
2. Sleep. Just do it. I have found out that lack of sleep takes me down hyper-focus lane. Great when you are alone and is tinkering along for a weekend. Not at all in basically all other scenarios. Hit bed before 11.
3. Eat and drink. Healthy and just enough. The effects are similar to #2 if I don't.
4. Physical activities. Go for a 20 min run. It is boring, but reach the point of proper sweating and keep going for another 10-20 min. The effects on me are amazing and in many ways resemble #5, only even better.
5. Breathe. Honestly, I have started practicing mindfulness and it just works for me. It takes me down into myself and allows me to spread focus.
On the bus right now, and this is what I can think of at the moment. Always a work in progress. I'll see about that blog...
