Plan. Plan. Plan. Plan,,, plan & plan.
Reach out to workmates,, neighbors. Go to a gym hang out with people at random at the shopping mall. Go to Starbucks!!
Sometimes,,, to have friends ,, you have to reach out and be a "friend".
I know., especially those who are born on the borg may lack social skills. But just socialize with neighbors or workmates. Spontaneous conversations,,friendships. Find a common ground & go from there.
