I am using my subconscious mind when I am losing motivation. This means that I do not try consciously and willfully to regain motivational drive, but wait until it naturally occurs as a result of my subconscious mind activating it again through repeating my daily prayer. But sitting there and turning your thumbs is also not very helpful, for your subconscious mind needs you to move forward, then it will connect to any other activity that is *not* demotivating you.
This is why I recommend to always do several things at the same time, because when motivation vanishes off for finalizing one, you may finalize any of the other instead.
It is important that the activities are not too similar, like writing one book on science, another being a poetic work, another still an audiobook, and other works involving cooking, cleaning or making order in one’s library.
Our intelligence is differently structured when different kinds of activities are involved. At the end of the day, if all this is still not motivating me, I can as well drink a good bottle of wine, play Mahjong, do a drawing or painting, or vacuum-clean the apartment …
You will realize when you follow my advice that times of demotivation become as rare in your life as accidents: for after all to be demotivated is an accident and not a natural occurrence.
