If your portfolio still holds pieces from your old career, you're in good company.
When I switched to illustration at 44, half my portfolio was design work. I kept it there because I was embarrassed by how little illustration I had.
A mentor helped me pare it down, rework what was worth saving and fill the gaps. Then I sent it out again, and art directors started writing back.
The 30-Day Portfolio Reset is that process, built so you can follow it on your own.
