Feedback Loops
Everything is dependent on feedback loops. Video games/reels have short exciting feedback loops. That is why they are so addictive. Real life often has long feedback loops. Anything you do, it will take time to see the results.
You will have to grind hard at something and for a sufficiently long amount of time to achieve something meaningful. Yet if your brain is trained to enjoy short feedback loops it becomes hard to do something for long without seeing exciting results.
You either train yourself to enjoy long feedback loops or you shorten the loop through regular rewards. Maybe break down the huge task into small chunks.
It is often good to run both a long and short feedback loop on a task. The long loop keeps you aware of the bigger picture so the setbacks don't seem as bad. The short loop keeps you on track and gives that constant nudge in the right direction.
You are already in a feedback loop whether you are aware of it or not. Better off being in a feedback loop that helps you grow. One of your own making.
