start by assuming that the person has the capacity to make their own decision
understand that because the person cannot make a decision in one area of life does not mean that they can't make decisions in all areas of their life
not assume that the person lacks capacity because of age, appearance, disability or behaviour
focus on the person's ability to make a decision, not whether the decision that they make is good or bad
respect the person's privacy
make sure that the person is getting the support that they need to make their own decisions.
