Time Travel
If you encounter a difficulty that you dare not face directly, you can close your eyes and imagine yourself as an elderly person in their 80s who is nearing the end of their life, full of regret for all the hardships they once gave up on and avoided.
You will tell yourself, “If I could be young again, how wonderful it would be to return to that past!” Then you can open your eyes, and boom! You have returned to that past you longed to return to.
Now that you are young again, you know what to do. ;)
