Money Thinking

Today my C is: My net worth is -$40k and have $4k in the bank
I want to go to the C: I have $100K.
How can I do that? I believe that I have the $100k and I feel that, but when I come back to now, I dont actually have the money and not sure how to act on this believe. How can I believe on the present not actually having the money?
If I really had the $100k I would act today in a different way. So believing that I have the $100k is difficult.
How can I really believe something that is actually not true?
Thank you for the help =)
