I have a lab-mate who is very religious. Every morning, before he starts working, he always reads what I think is the doctrine of his religion. Every afternoon, at around 4pm, he worships. I am not sure if it is an effect of reading the doctrine everyday, but he is very responsible, very hard-working (thus, a good researcher), and has a good lifestyle.
I am not religious. However, I am thinking of making a doctrine of my own, which I will read every morning and every night before going to bed. They might be the principles I will follow in my life. They might be some words that encourage me to focus on my work and my career. I think they might help.
