happiness is very linked to unexpected surprises.

I personally have been experimenting what basically amounts to a Christian version of Bhakti Yoga [0]

basically "wow, thanks God/Jesus, this is wonderful, I love you, you're awesome, thanks for X, Y, Z, etc". If you can stay in that mood of gratitude and occasionally add in a lil "and if I could get an A or B that would be great, but no worries if not", and... in my belief system/experience, the desired outcome happens somewhat effortlessly :)
