For me its always good to start your day early specialy surfing because if you're lucky you can go surf without obstacles or any crowd while riding a wave. Just like reading a book or studying you need to avoid noises and lock yourself in the room so that concentration and focus are there without any kind of distractions to fully understand each details that written on every page.
The imagination going through your mind to make a manuever is there and you only need to focus in working on it.
