I’m sure you’ve heard this many times especially when it comes to someone who’s serious about their career. Going out and having fun is always great but if you want to have that moment, you must first work for it even if it’s a Friday night. Sure I was invited to do something fun on a Friday night, but when it comes to a client, they come first before having a night out with friends. In many cases the client might consider their problem priority and can’t wait another day or two for you to provide them the service they need. If this is the case and you don’t attend to them when needed, they might go somewhere else who can attend to them and I would lose money and possibly a client depending on the scenario.
