Appreciation of famous quotes

Continuous learning is to cultivate the inside, and dressing up and decorating is to cultivate the outside. You should cultivate both the inside and the outside. Both are important. When meeting others, dressing appropriately is a sign of respect for others. Only when you respect others will others respect you. And those who only have profound knowledge and do not pay attention to their appearance will be rejected by others. In a society with frequent social interactions, grooming your appearance and heart also plays a vital role in career success.
