Write a letter to yourself to be opened in 5 years, or more. Ask questions and make predictions. Disclose hopes, dreams, and aspirations. Provide encouragement and support should you be needing it at that time.
Remind yourself of what life was like in this time, positives or negatives.
Put it in an envelope, write To: Future Me and put a note on the back of when it is allowed to be open. Then put it somewhere safe, and wait.
