Dear housemate,

I need advices on how to go about meeting a lovely girl to date. I am a young man with a good job; for like 3yrs now I have not been in any relationship. It was actually a deliberate attempt so I can concentrate on my career.
In recent times, I have started feeling incomplete without a woman in my life. I have decided to start dating again, but the problem is I don't even know how to start?
The questions are:
a) where should I hang out at my leisure time where the chances of meeting a good girl is high?
b) Is there any social media (chat) I should join to increase my chances of dating a GOOD girl?
Well Just thinking aloud, your advices is highly welcome.
Thanks.
