How does one become make themselves a better looking person.

Work out a lot. Get fit and wear clothes that fit. Get a flattering haircut. Walk and act with confidence.

I look so different than I did three years ago that an acquaintance I worked with back in 2014 and hadn’t seen in a long time asked (jokingly, but also I think not so jokingly) if I’d gotten plastic surgery. I have not. Just hit the weights hard for years.
