There was a time, thankfully long ago now, when my background philosophy could probably be summed up by, “I’d better not hope for too much, then I won’t be disappointed.”
This was a time when I generally expected that I had to work hard and then hope I achieved what I was aiming for, rather than working hard and seeing confidence rising from my actions.
Hope is good, but hope is not the word you want to have hanging around your viva. Don’t only hope you will pass: know that you will. You won’t be disappointed.
