Making decisions is hard work, and adults with ADHD struggle to make decisions more than most. Replacing decisions with routines gives you more energy. But, I often hear new clients (or people who’d love to be my clients, if they only believed it would work for them) say they can’t develop routines, systems or habits.
Some people have a greater-than-average capacity for decision making, just as some people have a natural advantage in certain sports. Of course, others have a lower decision-making capacity. Perhaps ADHD lowers your decision-limit.
