Can you elaborate on how you went about this? Where are you located?
I ask because as a single breh in his early 30s with no children and a successful career, my circle is so small it's a period (just me).
I didn't try to lone wolf it but it ended up like that anyway. I moved cross country straight out of college for a job and I worked hard to turn that into a dream career. My social life suffered as my career took off, with work forcing me to have unwanted social interactions as the token breh in my IT area and when I did meet brehs outside of work, it was always on some "shyt, I'm trying to get like you" (I'm actually mentoring a few younger brehs I met this way). All of my existing friends back home had kids early and none of them got married so just the BM drama alone separates us but that's just the beginning.
I'm hoping moving back east within the next few years will help (I've heard good things about black professionals in DC for example) but I don't want to wait till then so I'm open to suggestions and curious to hear if others had similar challenges
