Yes! Yes! YES!
Tom is spot-on here: you shouldn’t be afraid of writing about yourself …especially not for fear of damaging some kind of “personal brand” or pissing off some potential future employer.
If your personal brand demands that you live your life in fear of disclosing important parts of your life or your experience, the answer is to reject the whole sodding concept of personal brands.
Do things I write about my personal life threaten my personal brand? Perhaps. Are there people who wouldn’t hire me based on things I write? Probably. Do I give even a whiff of a fuck? Absolutely not. I wouldn’t want to work for them anyway.
