Can someone point me in direction on how to lead conversation in a club/lounge while approaching someone?

This is more in regards to self-work I need to do. I hear/guess people usually talk about following (with how this doesn't apply to me):
1. Music/Movie: Most of the music I listen to is non-english.
2. Sports: I don't follow any major sports.
3. Some bad incidents story i.e. How someone was being jerk/stupid at a restaurant/work/street etc. That's not my style. I don't talk about any negative incidents much.
4. Sexual flirting: I'm not good with coming up witty comeback.
5. Travel: I haven't travelled much in last 6 months.

 

This opens up a whole new horizon to work on myself and to begin with I started to look at my lifestyle.
1. Excluding my work where I spend most of my prime time as it's not that interesting to speak in public.
2. Read majorly non-fiction, specially human psychology.
3. Meditation.
4. Tennis.
5. Dance.
6. Cook.
7. Watch comedy shows, thriller movies and documentaries.

 

Can someone give me some pointers on how to lead conversation, please?
