If you’re feeling unsure about a new person today, by all means don’t get involved with them. Even if they’re influential and could help open some doors for you, it isn’t wise to go against your instincts right now. Wait a while longer and get opinions from people you trust about what they think of this person. If things are on the up and up, their invitation won’t go away. In fact, they will respect you all the more for doing your homework.
