1, go to the street and find a girl to stand next to her for ten seconds.
2. If a girl looks at you, smile at her.
3. Say hello to her.
4. strike up a conversation and say: I want to know you until I get a girl's contact information.
Ps: Every step above is until you feel it won't be embarrassing. If you feel embarrassed, go away.
