another thing that I had noticed is that is when i learn something and i expect dopamine earlier than it given by activity i seek it in other places instantly.
like listening to something promising that gets boring people seek Facebook instantly as dopamine is not delivered instantly.
so solution is to deliver dopamine every short attention span people have.

one solution is to to deliver the dopamine in timely manner. if it is learning to deliver understanding fast as expected.
another solution a i saw on videos by Shai Reznik at he shows every now and then a funny picture in not taking away attention way.
Shai is very good he delivers anyway!
