Or what you admire about them?
I've got 16 month old twins who had a very rocky start in life. They were very premature and almost died at birth and spent weeks in hospital. Fast forward to 16 months old and they're very physically active. I admire the fact that if there is something they cant do, they will keep going back to practise until they can - they don't give up. If they fall over, most of the time they just get up, dust themselves down and try again. Its probably just a toddler thing but i think its a good lesson for me!
