I agree one should learn but with him it's not lack of motivation rather a lack of coordination for this type of thing. He has mental illness and is borderline autistic but very functional otherwise. It's the calculations that he's bad with.But as long as I understand from your post, you built the rda for him. I mean, it's fine if it's ok with you, but motivation lacking is bad policy. Unless elderly or disabled, the easiest route to success is to let each person learn on their own. I don't build things for my husband, he has learned and now builds himself.
