My tip is to get out there! Be yourself but grow yourself! Go out and add new, different beginners courses to your routine. Courses usually run like semmesters but for say tennis school, learn to swing dance, cooking courses, drawing lessons, tai chi, swimming, etc.. They are usually cheap and the point is stick them out and attend the whole course (no matter if thèy suck) but change them when they end (unless you want more of it!)

These courses may have no one you are attracted to in them but that is not the point! The benefits are..
- You are learning. You are increasing your skills and knowledge, instead of just watching it all on your colour tv.
- You are meeting new people. You can learn from the lives of others of any age.
- You become more confident in new situations. Like that "i forgot your name from last week" moment or asking questions.
- You may find a hottie there and you already have a common topic. Yay!

^Look at all you gain from the list above, all of it carries through to your daily life and is useful and puts you in good stead when you do miss your train and bump into someone special.
