Guys, Should I do it?

So, i have this crush in a grade above me. I've never talked to him since almost a year back. But i haven't approached him or anything because i dont know him and i dont have the courage to do it. But should I like give him a smile or something next time he walks by? Im afriad that he will just look weirded out or think that im a stalker. What should I do?
