Some sort of diary as above would be useful, certainly.
I'd say try to keep in touch with people you got on well with when you were younger or get on well with now (which might require use of facebook etc, of course!) When people go off to Uni or other training, get married, get a new job, move to a different area etc, all those social ties can be severed, which is sometimes a blessing (!) but sometimes a shame. My daughter lost touch with some of her school friends but found them again through social media after a gap of some years, and now they get together every so often and have a great time. I met my oldest friend fifty years ago (argh, I feel old!) and our friendship has d its ups and downs, but survived all sorts of hassles and separations. Good friendships are worth nurturing, and could well last all your life - a vital support network in difficult times, and a source of joy in so many ways.
