Achieving something:- like writing a new Folk song that everyone likes and seeing them pitch in and enjoy it.
Growing a new hybrid flower(or weed)
Creating a new food dish.
Making a new friend.
Taking time to eat good food.
Going to Folk evenings and Festivals.
Getting much needed exercise.
There are many other things but I have only really got round to doing them since taking early retirement...Loving every minute and wondering how I ever found time to work.
Best wishes.
