Programming

Hi I am Shalin Shah and I am a 13 year old kid who just started coding. I started web design 4 months ago and created middleschoolnotes.org and now I am learning Objective-C (http://www.shalinvs.tk/learning-objective-c-day-one) and I built Ideya (ideyaapp.tk). I would like some advice on how I can be a really great programmer. I really enjoy coding and I want to be the best at it so I decided to ask somewhere where everyone is really good. Thanks!
