Poll: I'm a noob programmer - What should I focus on to become better?

Following ScotterC thread about what makes one a good programmer (http://news.ycombinator.com/item?id=4759510) it got me thinking.

I am a starting programer, programming mostly for iPhone and Web. When I work as a freelance with customers they'd say I'm the best. When I work with fellow programmers on the other hand they'd say I am the worse.Trying to get better, It would be great if you could help me understand what makes one a good web or mobile developer?

Could you please help me rank these?

1. Simplicity

2. Readability

3. Abstracting a problem

4. Encapsulation

5. Code efficiency

6. Speed \ Quantity

Am I missing any other parameter?

Thanks!
