Be On Time

It shows self respect, that you’re organised, and that you respect the other person’s request and their time.

And by being on time, that means show up 5-10 minutes early. Then there is no argument about whether you were on time or not.

It also indicates that you think that the person is importance and that you value their time in your life.

Of course the opposite to all of these is also true.

Be on time.
