1. Nobody is actually too busy to respond to you
That boy or girl isn’t too busy to text you back. And your potential employer isn’t too loaded with work to get in touch. Remember, people make time for who they want to make time for. We text, call, and reply to the people we want to talk to.
If you don’t get a response from someone it’s because they have deliberately chosen not to answer you. The sooner you stop making excuses for people who treat you badly, the sooner you can get closer to the people who respect you
