Even those who've been through lawsuits know that the experience will eat them up hours of time and cause them serious emotional capital. To cite a personal example, when I drive my car I know that I must carry enough insurance to protect my assets, not the minimum necessary to satisfy the law. You plan, before you commit. You protect before you risk. You can do it with a minimum of hassle.
Planning is an exercise, like other exercises.
Furthermore, you do almost the same activity every time you plan. The more you do it, the better you get at it. I like to compare planning to working out at the gym. Planning is a skill that's always in demand because most people fear it and, to paraphrase Henry Ford, most people don't like to think, let alone plan. Remember, the secret to not getting sued is to plan before you act or commit to act.
