i know that im wrong in chasing people but if i stop chasing them no one chases back.. but i want to have friends too

i know im not boring.. i have hobbies and a job. but i judge my self based on how others reply to me or talk to me
i base my self worth based on how much attention i get
from others... 

i know to get attention from others is not wanting it.
i want to stop pleasing others just to get attention but how?

its like i dont exist. i always start conversations. ask more questions.. do i ask more open minded questions? do you guys find conversations hard also??

i run out of things to say or talk about. i run out of topics pretty quick also.. i dont know what to talk about!!
i know i need to practise more but its like i want to practise driving but i dont even have a car!

i know people have problems too but i always feel like they are better/cooler/funnier/smarter than me and better in convos than me.

what do you guys say to yourself when you see other guys with a gf?
