I've seen many posts on here telling everyone to write. Write something, get used to it, help to better foster communication skills.

So I have a question! If you were just at the starting of your development career, what is something you wish you would have talked about more? Was there something you wish you had a log of during your personal development? I'm looking for ideas of what I can write about, and more importantly, what would be interesting to read for others! Thank you to any responses.

About Me: I'm very new to programming and development, as I have less then 6 months experience with coding, however I have been studying very diligently during that time as I am out of a job with other issues. Before this, I got a degree in Illustration, so the design side of web development is not foreign to me. I'm looking to make a career change, and so far have gotten an interview that went well for an internship!
