In the end, it is those character traits that understanding, caring and empathetic people possess that I think, if a developer has more of, will make the software product better. So learn those soft skills. Get good at them. Train yourself to be a better listener. Train yourself to put the end user's needs before your own. Help and mentor your team mates. Take time out to help them. Remember, you are building the software for the client. Reach out to them and try to solve their problem. Make them part of the process. After all, you should be developing your software for their needs and not your own. You should be trying to help them and make their lives easier and remember that it takes a village to raise a software product.
