Habit building is indeed no joke. It is an excruciating task which is repetitive, mundane and requires plenty of motivation to keep it running. I personally struggle to maintain 9 hours of productive working each day. But, the motivation should never end and one must never stop trying.

It begins with baby steps, slowly progresses, and then turns into second nature with time where one may not even realize that they have achieved their said tasks. That is how habit formation happens.
