"Help Marc, I have made terrible coffee all my life!"

Question: I need help - I have made terrible coffee all my life. I have tried everything from Melitta to french press to a Capresso auto drip coffee maker and I can count on 2 hands the number of times it has been good in 40 years. I really appreciate a good cup of coffee, not strong but flavorful. Can you help? I have resorted to exact measurements of water and coffee and still it is awful. Please give me some detailed direction on how to make a good cup of coffee. - Sue
