It is obvious that if we are asked why we believe that the sun will
rise to-morrow, we shall naturally answer ‘Because it always has risen every day’. We have a firm belief that it will rise in the future, because it has risen in the past. If we are challenged as to why we
believe that it will continue to rise as heretofore, we may appeal to
the laws of motion: the earth, we shall say, is a freely rotating
body, and such bodies do not cease to rotate unless something
interferes from outside, and there is nothing outside to interfere
with the earth between now and to-morrow. Of course it might be
doubted whether we are quite certain that there is nothing outside to interfere, but this is not the interesting doubt. The interesting
doubt is as to whether the laws of motion will remain in operation
until to-morrow. If this doubt is raised, we find ourselves in the
same position as when the doubt about the sunrise was first raised.

An INFJ is prone to hold him/herself to very high expectations and have an urge for perfectionism. These tendencies allow us to succeed and attain great achievements. However, they also can cause lots of unnecessary stress. Thus, the INFJ must be aware and learn that perfection is not always the best and that it’s fine to mess up or fail.
