Being really good in your field is important, but more important than that is to seem to be good. Invest in yourself. Be searchable!
How many times did you search your name on Google? How many times did you search some keywords related to you? Did you like the results you got? Can them be better? They should.
We, developers and engineers, built the Web like it is today, but sometimes we forgot how important we are, and mainly, how important we should be. This is something that – believe me – happens more than you think. We like to code for others, to create software, to make money, but we forget to invest in ourselves images, and how people think we are.
This is not about your work, this is not about your job. This is about you, your image, and how you take care of it.
