Unless you absolutely hate the act of writing, or are just an objectively terrible writer with no intentions to improve, you can really benefit from having a blog.

You can use it to write about what you're learning, or jot down your ideas, or post travel pictures, or even videos where you talk about the latest project you're working on.

There are absolutely no rules to what you can put on your blog.

You just need to give people something positive to read and look at when they Google your name.

Why?

Because it can help establish trust before employers ever talk to you.
