Take it a step at a time. But when new things cross your mind that you’d like to do someday, take action. Make it happen. I am so very lucky because I have two friends Jim and I have known for years, and they invited me to go with them to Yellowstone, and the Canadian Rockies by train after Jim’s death. I didn’t hesitate, I went.
Don’t wait for someone else to come along and invite you. If you do, you may never realize your dreams. I can honestly say that I have had a wonderful life! If it ends today, I would have few regrets. Don’t waste whatever time is ahead of you.
