An interview with JJ on Chopin airport. It's in Polish but he basically says that right now its important for him not to get carried away with all the media attention and people's expectations, focus on himself and work hard on his tennis. He also says he plans to rest and relax for the next few days.
At 1:10 they ask him about 'a certain lady' who was in his box during SF, if she'll help him relax and how their relationship is going and he pretends he doesn't know what they're asking about
Eventually he says that 'it's okay' and he also looks a little flushed while doing so
That is good that Jerzy isn't going to let all the media and expectations get to him...Now that he is has made a GS SF, alot of people will expect him to keep doing well, go deep in tournaments, win titles, etc
He is in the Top 20 now so he will be expected to break the Top 10 next
He just needs to stay down to earth, keep practicing hard, stay injury free and not get too cocky or overconfident after such a great breakthrough/result at Wimbledon...
The hardcourt season is coming and he needs to practice for that and get better on outdoor HC
Stay level-headed Jerzy and don't let the pressure get to you
