I would like to expand on the "try things out" approach.
Do you know of the book "1001 Places to go before you die"? The following method is similar. Take a sufficient large piece of paper and make a numbered list of 1001 thing you would really love to try before you die. You may not reach that number, but the point is that you have plotted some starting points.
Now take several of the items from the top of the list and try them out. You may use the "Backward Planning Flowchart" by Barbara Sher to arrive at the action steps.
