That`s the beauty of this job you can do what you like within reason,i prefer to run it more like a business it keeps me more motivated that way.It`s a lazy mans job if you want it to be as it can be fitted round your social life or church,it allows you to live a stress free life to a point and once you get beyond that point you have to choose which way you want to take it.If you don`t want the stress you have to learn to say no when the phone rings for new work,if not before you know it you have more work than you can handle.
