If making lasting friendships is what you're trying to do, I've never seen that as being an easy task.
Long ago I was told that "friends are there for the good times," and more and more in my life this has held true. Friends are nice to have, and everyone needs a social life if they desire it - but it's also a fleeting desire, as very few friends will be those whom stick around for life - or even for the next year, and make time to see you.
That said, I've found the best friends to be those with whom you bond over some kind of activity you can do over again with them - whether a sport, or a hobby. At the very least it's something that will bring you two together.
