Going back to Uni at 31 and getting first in Design/Engineering BSc, despite working and doing a few other things.
My Daughters (aged 6 and 3) the older one is a coeliac and drags her arse to School everyday even when she is feeling rubbish.
The little one had a terrible start in life due to birth complications, however she is a tough little bird and continues to shake off all the ailments she had at birth.
My Mrs, as she works her arse off, and looks after me and the kids.
My sister-in-law for supporting my little brother though 6 years of cancer (sadly this journey is about to end, and not in a good way)
