1, two people live together, it is best to first understand the main shortcomings of each other. (When a bad mood, will be silent, sometimes lazy, clothes will be put a week to wash;)
2, the best understanding of human is the first to understand the specific individual.
3, the human brain is a limited space, you must have the choice to absorb knowledge, you can not put anything in, so do things stupid. If you do that, you will lose useful things, at best, for many other things to mix up, and also difficult to apply. Therefore, the person who will work must make a very careful choice, remember what is useful to him, throw away all that is useless, and make the useful things rational. It is wrong to think that the space of the brain is elastic and cahit any expansion. Please believe that someday, as your new knowledge increases, you will forget what you used to know. So the most important thing is not to let useless things repel useful things.
