I wrote this post for those who have hard time with loneliness and rejection. My advice is have confidence and believe in yourself. It doesn't matter what you talk about its all about the conversation atmosphere and flow light heartedness and fun goes along way. Never approach anyone with ulterior agendas. just get to know people and let relationships grow . Learn astrology ladies love that stuff.
Make small conversation for example : hey, its a beautiful day , how are you today?
depending on their reply lead into more topics and ask questions that promote happiness and joy, memories on hobbies, events , music, art etc etc eg. what music are you vibing with lately? this is a good question because you can guess other things they would like based on what they vibe with. listen and understand what they say!
Embrace rejection! it builds character. when you are rejected from the most beautiful smartest lady it makes approaching women easier and easier . no matter what always know you are loveable and loving. It can be soul crushing! but everyone is perfect their perfect partner, you just have to be realistic and down to earth. respect is the most important thing.
Just say hi and read the body language . Toxic masculinity has made all approaches by made very uncomfortable. try not to make people uncomfortable its all practicing social skills.
