What is the most important knowledge in life?

Living a life full of twists and turns, requires knowledge. What is the most important knowledge? The answer is Religion. Why? Because religious knowledge covers all aspects of life. I believe
there is life after death, it is very important to pay attention to, and only
the most complex religious science teaches us many things, such as ablution,
prayer, fasting, giving alms, paying zakat, marriage, friendship, and many more.

After that what? Social studies. Because we are social creatures. We really need to socialize with other people, without it life becomes arid and scary. At least with social science

we are not alone, we are happy together, not worried about being difficult
alone, look at the people below us, then we will be grateful, and
look at the people above us, we will be motivated.

The third is economics. This science
is related to finding enough income to live. Studying about
products needed by humans, human spending and so on that
relate to fulfilling basic needs, such as eating and dressing.

The fourth is entertainment or
entertainment. What this means is that humans need entertainment
such as singing, reading books, farming, writing, video editing, cooking,
to fulfill their inner satisfaction.

Finally, the fifth is the science of
psychology. Humans need to be sane to live, not crazy or stressed, because life becomes chaotic. People need a lot of things in life, but the most important thing is their soul, which must be friendly with all
circumstances, not easily worrying about things, then their life will be calm.
