What if the only real problem was that you weren't ready back then? You're not the same person you were 7 years ago.
Best advise I think anyone can give you is go through the course as if it is your first time. This time look at is as if you're opening a new video game.
I like what video games teach you, I don't play them but I like how everyone just accepts the learning process as a challenge. In the beginning they last something like 10 minutes before they see game over and what does the player do? Start again, last a little bit longer and then it's game over. Then in the next couple of games the goof and don't even last as long as the first time, makes them even more determined to get to the next level.
At any time have they failed? No, of course not, it's a new game a new challenge. Learning and playing a game is how we need to approach any learning experience. We always seem to think it's the end of the world if we don't get it right the first time and yet the world ticks on. To learn PhotoReading is a lot like opening a new video game, it's unlike anything we were taught in school and our curiosity should be like that game playing individual, challenge yourself to reach the next level. Go easy on yourself, like in playing a game there is nothing to fear and each time you play it you get a bit further than before. So have fun with it.
