Once upon a time, at a social work camp not too long ago, we went through a group exercise where we wrote short letters to ourselves, to be posted by the camp organizers back to us 6 months hence.
This is the letter I wrote.
Dear CD,
Hope you are well.
You are changing your job soon, and tendering your resignation. You will have finished your internship attachment at an as yet unknown place. The attachment will have changed you, as you have hoped for change, and I hope it has changed you positively, though it might not seem so now to you.
I have just spent 1.5 days in the social work camp in (month), and we are now supposed to write motivational things to enable you to live better in this time.
I can only say that I trust your judgment and that I believe in you, always. You will be a very good social worker, even though you are just starting out. It is more than the doubt that matters, although that is important as part of self-reflection. It is the heart.
Yours,
CD
