Overwhelmed by your workflow? Reset it.
Productivity and organization workflows can quickly become addictive. If you like apps and all that comes with them, your workflows can snowball out of control. I run into this problem every couple of years, and until I become aware of that, I feel very frustrated. I feel like I am moving around a lot of stuff and spending many hours of my awake time producing nothing more than heat and entropy. Luckily the solution is easy: do a total reset.
You need to decide your decisions
If there is something that I learned from my daily struggle with procrastination, is that every day you just have a limited amount of decisions. Every day, you can only do 5, 8, maybe 10 meaningfully decisions. After that you will start doing mistakes, get tired and, in general, doing wrong.
What can be surprising of this, is that doesn’t matter how important the decision is. Look at a traditional day: you wake up and you need to decide what to eat for breakfast, what clothes to wear, if it is better to go to work using the car or public transportation. You have literally just waked up and you have already depleted the big part of you decision pool for the day. And none of that decision is meaningful for your work, your career, your family, your affections.
On developer anxiety
You are finally back home. During your work day your mind was totally a volcano of creativity. You have so many cool ideas to implement (or at least to sketch). You go to your machine and you start to thing to the technical details. Many questions reach your mind. Maybe too many. Is it better to use Python or Haskell, or maybe C++? I have to start implementing my game prototype with Unity or with some other engine?
