Just be yourself and don't pretend that you want to impresse him act as if he is just another friend ...don't over do and be a friend first don't go on asking about what he likes and dislikes its just too old start the conversation with a hi and keep it intresting and don't make him feel like your stalking him don't call him more often just once a week or twice and when you'll become his friend he will automatically start showing his intrest in you...
Just be cool & be yourself. Just speak as if you r talking to a regular friend & don't try to jump . Go slow. It'll work!!!
Try to keep the conversation going ... Think of topics and crack jokes frequently.
Just be yourself... Try to tell him about your own likes and dislikes instead of asking about his likes because that would seem more of an interview... Once you tell him about your likes you would gradually come to know about his interests and in that way you would be able to start a topic that would seek his attention... But please don't go on speaking bla bla bla about yourself and don't over do because he may feel passive, just let him participate actively in the conversation... When you get ruined of topics to talk about let him start the conversation and just play safe!!!... :-) :-) :-) good luck...!!!
Be frank don't lose your atituet.
