Face to Face Meetings
Nothing beats face-to-face meeting. Even though the internet and Skype have made it possible to work on a project over long distances without constant personal meetings, meeting a client in person and spending an evening together at a restaurant or bar will most of the time make a big difference in your working relationship. If you are a person that is generally fun to hang out with such a personal meeting will most likely do more for your career and future projects than months of writing emails. So as a general advice, whenever you have the chance of meeting a client in person that you want to work with on more projects it might be even worth doing some extra effort to meet them (even if it involves a trip that wouldn’t be 100% necessary).
