You've been given one-time access to a time machine to visit your younger self. After a brief pause, you know the when and the where, hop in the machine and take off. When there, you chat with your younger self but offer one piece of advice to him/her that you hope will change his/her future for the better. Start with your arrival in the time machine (and what does your time machine look like) and end with your arrival in the future noticing something that has changed.
