their is nothing wrong in being single, its not the end of the world.
i dont think their is much for someone to do to find that special one.
as long as you're open to meet those new ppls and don't have programmed judgement about certain pple things should be smooth.
i am still 25 years old and i am with a special one but i didnt knock ma head to the wall to get here, it just happened.
relationships seems to be like that in generaly, my advise is to socialise and be open minded.
an 30 is not old, 30 is pretty young and hot no need to fear :)
