Flatmate Dilemma

Hey, I am in a great dilemma recently and needed some advice. I am entering the corporate world from college and moving to Bangalore and now look for a flat but greater decision is to find perfect flatmates. I have been living with my college friends and feel that i don't want to live with them anymore because of what i have faced with them. I feel like they haven't yet come out of college and their life is quite monotonous, waking up -> going to office-> coming back -> watching movies or IPL and then gossiping till bed time. And of course Friday Saturday mandatory alcohol. I am good friends with them and want them to be by my side but what I want more is that I have flatmates whom i can learn from, with whom i can discuss ideas and with whom i can build something. But how do i find these people? What should i do so that i get in a company where 5 people around me take me higher in life. Need some guidance. Anybody? PS- Obv I care about my friends and in my opinion wherever i live, i can go back to them whenever i want.
