So I've written - and spoken - about how we should all be blogging as we learn things. It's a good idea for many reasons, some selfish and some altruistic. But I've always said: you really should try and write as you learn something.
It’s easier to write about a topic when it’s fresh in your mind. If you mean to write about something later, it can easily become an item on a todo list that you’re likely to put off and not get to. If you’re able to fit writing into your schedule – please try to. Even if you keep it private, writing is a wonderful way to document knowledge and gain a deeper understanding of the subject. I encourage you to try it out, even if writing hasn’t been a strength for you. I have faith you’ll produce something of value.
