Living, playing or working alone, without regular communication or physical contact with other people can weaken your spirit, may be self-defeating and could cause unnecessary anxiety, stress and self-doubt. Feedback and the sharing of thoughts and ideas help people people to succeed, invent, be creative and continue the learning process throughout people's lifetime. No matter what line of business you're in, there are multiple companies out there in the same line of work that share similar customers, terms and conditions, economic trends, policies and procedures. By constantly building up your network, you continue to assemble a stable of contacts that you can call on in the future. You may even be looking for a new job one day and now you'll have many contacts to reach out to.
