I've read countless articles, blogs, and tweets about how one should never compare themselves to others since everyone's experiences and aptitudes are unique and we don't know how much they struggle before reaching their goals. And it's bad for your health, mentally speaking.
While this advice sounds good and all, then how do YOU measure your own level of competency as a developer?
Do you ask someone who's more experienced than you to assess you, or do you have own methods to assess your programming skills?
I'd love to hear your opinion.
