Streaming videos and reading answers will not directly help you in solving the problem of procrastination until and unless you want to take step. Procrastination has a simple treatment. If you feel like procrastinating just do the work no matter what. Sit on the chair and start studying. Practice this for some days and you will find that these habit is dissolving. Also be aware of the food intake. If you have lack of energy then also you can procrastinate due to weakness and lethargy.
