What types of questions would one put in a "dear future me" letter? i'm very stumped on what i should say/ask. ideas would be much appreciated.

In my future I wish to see myself as (career)
I wonder if I will have a good job/wife/kid/grades

If you're writing a letter to your future self, think about questions that past you would have for now you. Maybe you would wonder if you were still friends with someone, or maybe you would be curious as to whether you're still on a particular team or doing a particular sport. Anyways, it isn't very difficult. Just write like you're writing a letter to a friend

Friendly , good-natured , or easy to talk to
