Attributes Of Highly Effective Programmers - Quality Of A Developer - Self-criticism

Today I had come across two articles and I feel that its good and all the programmers should read this articles.I like to share this for my blog readers.I'm posting the abstract here, so through the orginal articles.

Top 5 Attributes of Highly Effective Programmers

  • Humility
  • Love of Learning
  • Detail-orientedness
  • Adaptability
  • Passion

The most important quality of a developer: Self-criticism

"Don't just implement the first design you come out with, but try and refine looking at it from different angles before to start writing code.

Don't just release the first piece of code you come out with, but do a self review and try to make it clearer and better.

The best developers/architects are the ones that always criticized their own work in order to make it better."
