I got excited and purchased shares in WHS when they announced (prematurely) that they would be open during lockdown. It was a complete departure from my plan (to invest monthly in ETFs this year), it wasn't a company I had any interest in before, but I was flustered and reading the news (I know, I know).

Managed to break even selling a few weeks later, but learnt a swift lesson about not letting emotions drive purchasing.

Other than that, I wish I had purchased some more A2M.
