Completing something hugely rewarding when you have the energy on a consistent and regular basis allows you to avoid feeling tired all the time because it will make it okay for you to make small progress doing very easy and small stuff or tasks for the rest of the day without feeling like you are doing something wrong or not doing enough or that you’re wasting your time, because you’ve done something amazing at the beginning of the day or whenever you had good enough energy levels, and since you didn’t have to grind too hard all day long, you will not be depleted, drained, or exhausted every single day in order to keep making progress. 

You have to understand that it is not just Dopamine or Serotonin. It is deserving the Dopamine or Serotonin. It is being allowed now to be flooded by Dopamine and Serotonin, because you have accomplished something amazing today or recently. It is Dopamine or Serotonin, when you feel and know you’ve done enough. It is about your most recent progress being good enough. It’s about achieving and accomplishing enough, and making enough progress, according to what truly counts as progress or accomplishment or achievement, according to your core values and what actually is important to you and matters to you, and makes you feel alive.

If you don’t meet that threshold, that minimum amount of progress, achievement, or accomplishment, you will suffer from starvation from reward, even if your body has and can produce an endless amount of Dopamine, Serotonin, and reward chemicals or material. Which means, even if you managed to obtain that Dopamine hit through natural sources like doing any pleasurable activity that you like or enjoy, this will not solve the problem or satisfy the hunger for achievement or reward.

You spend your whole day trying to meet that minimum threshold or amount of achievement and progress needed, by doing small stuff all day long.

This leads to insane levels of exhaustion all the time, because you’re working all the time, and you are still not satisfied. You are still not meeting or satisfying your needs for achievement, progress, accomplishment, and reward, enough.

So you keep working all the time, which leaves you depleted, drained, and exhausted all the time, even at the beginning of your day.

However, if you aim for accomplishing something massive in a certain duration of time that is way lesser than all day long, like something that takes a couple of hours only for example, you will find yourself way more satisfied, even if it was way harder to do. Even if it requires infinitely more energy and focus to accomplish this thing. The fulfillment and satisfaction that follows afterwards will make it okay for you to aim lower and only do small or easy tasks or things for the rest of the day, making the rest of the day easier for you, which will make you not end up being as exhausted, drained, or depleted at the end of the day, because the rest of the day after accomplishing that major huge thing or accomplishment was almost identical to pure rest or regeneration time, in terms of energy spending at least, or how hard, challenging, exhausting, or energy consuming or demanding it was.

Do something amazing, take the rest of the day off. It is easier that way, and more fulfilling and rewarding, even if the initial task or thing you did today was insanely hard and energy and focus demanding.
