You may have heard it be said that the perfect life is because of perfect days. Perfect days are simply an outcome of perfect rituals or routines you do consistantly.
One of the key messages I got from the book OWN THE DAY, OWN YOUR LIFE: OPTIMISED PRACTICES FOR WAKING, WORKING, LEARNING, EATING, TRAINING, PLAYING, SLEEPING AND SEX by Aubrey Marcus (on audible) is the idea that the variables that make up your life interact with each other and cannot be separated.
He explains in his book that every variable in your day interacts with each other thus you should consider everything in your day as a whole. For example, if you wake up after having little sleep, you will be sluggish and may have a crap breakfast as you feel it will boost your mood. You eat your unhealthy sugary breakfast before getting in the shower. You become even sleepier after the shower and sit down to try and rest a little bit. Because of this rest, you fail to exercise to boost your mood and fail to journal due to time constraints. You end up having not enough energy to tidy and clean the house and have to rush to work. At work, you have a bad day all because of your lack of ability to apply yourself and finish in a grumpy mood. You come home to a dirty, unclean house which affects you further and you end up skipping your evening meal due to feeling too tired to eat. You go to bed ill-minded and have one of the most unproductive days of your life which carrys on this downward spiral.
Instead of thinking about having the perfect diet or perfect exercise routine, you need to look at EVERYTHING and do it all on 1 perfect day.
