Keep Promise
A strong personal brand is something that each person may develop by keeping their promises. As a result of the low value placed on commitments and promises in today's culture, people are hesitant to give others their trust. As a result, keeping promises helps to build trust. Even worse, many people break their pledges to their family and loved ones because they believe that "relatives should feel sorry for me".
Keeping promises seems like a basic thing that everyone can do, but in reality, some people forget about it or see it as unimportant. It is a wrong thought because if you break promises many times, you will lose credibility in the eyes of people. Especially, when you go to work later, if you don't keep your credibility, it will be difficult to work with colleagues, partners, etc. That will make your relationship worse.
