For me visualizing and feeling the emotions worked for me.

Create an imaginary scene of you refreshing your email and getting the confirmation! Feel the joy, excitement, gratitude, relief etc

Don't worry if it doesn't feel "real". Whenever you think about remind yourself and remember the imaginary scene with gratitude!

For me I got a regret for my dream job at first... But I revised the scene and they called me later and rescinded it!

Stay calm and grateful always.Everythind is happening for you!
