Grow your facial hair, put some effort into your style of clothing, start doing pushups, bodyweight squats, and pullups regularly, lose weight if you have to, and put effort into meeting women. Even at my fattest, there were opportunities to date, though rare, so it's not all about looks There are women out there, especially in their 30s, that really want a man, no matter how much they say they don't need one.
I imagine at 37, you have your finances in order, right? Your own place, a car, and money for a date is all you need. This racist country had me broke for a very long time. No one put me on, grew up in a city with zero economic opportunities, zero night life, horrible public transit with nothing in walking distance, and parents didn't help. With time and experience came wisdom. I figured out how to properly purchase (what to look out for) and maintain a car, went to the 6 certs forum for ideas, got free money from credit card rewards and savings accounts, and took advantage of crisis times lol.
Anyway, time is of the essence. Live this life before it's over.
