Is it naive to be too serious?

I personally don't think so. Naivety means immature thinking and acting like a child who hasn't grown up. Earnestness is an attitude towards life. Perhaps taking something too seriously will make people around you very puzzled, but this is definitely not a kind of childishness.

I also think that being too serious can be divided into many kinds. Some people haggle over trifles. For example, in normal life, some people don't want to suffer any losses, and they are especially serious about little things. They can figure out those little things clearly, so clearly that they can't lose a little. For example, shopping everywhere in life, especially in supermarkets, can not be less than a penny. I think it's stingy, but it's nobody's fault.

Other scientific research is particularly serious, so serious that it is necessary to calculate the number to many decimal places. For example, I usually do experiments and weigh a few milligrams with an electronic scale. At this time, I must be serious. Not being serious is irresponsible for the experiment. I remember when we did a group of experiments last week, the final result was 99%, but our group was 94%. The experiment teacher said that we failed and had to do a new group. I think we are particularly serious about this experiment at this time. I think this is a rigorous attitude, not naive, too serious for me, my team members and the experimental teacher.

Others are so serious that they have to be sinners. At this time, we will say that they don't know how to be human, have never experienced social repression, and are naive to ignorance. Is this really childish? I personally don't think so. Such people are responsible for their own lives and work.
