I was at a conference last week and ran into Ed Leighton-Dick. Ed started a #SQLNewBlogger challenge back in April and I participated, promoting the event and getting a few people to blog that month. Since then I've tried to keep pushing and managed to get 3-4 people to keep going.
Ed has kicked off a new challenge for November, and I think it's great. I'm issuing my own here for people that might not be SQL professionals, but work in another industry.
Use November to showcase your knowledge and write one post a week. Take some aspect of your job, something small and focused and spend a few minutes describing how you solved a problem or what you learned. Imagine this is a short answer to an interview questions.
I won't ask you to publish it, but keep it around. Make a folder somewhere and store your post. This will be something you review before you go to your next interview, so take it seriously.
Write one a week and keep them ready to give your career a boost when you need it.
