hard = many easy complexes combined

 one of the possible reasons for as to why something seems so hard is because it uses several easy to medium level components which you are unsure of... leading you to think that it is hard. So, in such situations, just break the wall by finding similar easy stuffs.. conquer them and learn what extra things constitute the hard job. Name them.. Naming something weakens it. Then master it. practice hard. Then the hard thing would seem easy to you.
