Hi Kasperow

You're going through exactly the kind of self-doubt that has dogged countless others including me. If you want to see my faltering progress please look at my youtube channel and it might just make you realise you're not alone. I hasten to say it's an honest record of my own humble journey but you might find it useful. There are far to many uber players out there who make ordinary folk just give up, but if I can become a better player then there's hope for everybody!
Until you make a breakthrough you'll keep on feeling the same but just know that it is possible and you'll soon gain confidence.

Good Luck!
