Something to the younger crowd...
Don't let the search for a significant other be your only motivation. Look, certainly, love favors the active, but there's a line between activity and obsession.
Life is too short to focus on one thing alone. There's so much out there, so many wonderful things to see, to feel, to experience, that narrowing your focus so much really cheats you out of what life has to offer. Have a goal, but also have a hobby, give yourself something to do. Go out, look for new places, walk in an area you've only driven past, take the back roads home. There's a lot of beauty in life, and we've only a short time here to see even the smallest glimpse of it all, but see all you can. Enjoy your life, have fun, because once its over, that's it.
Live your life, and enjoy what you got, because you never know when the ride's gonna end, so take from it what you can.
