Hackers do everything they do for fun. If it's not fun, it's not worth doing. It's important to note that fun things can be hard and very challenging, be it a grueling mountain bike ride or taking an idea all the way to a multi-billion dollar acquisition. Talking about how difficult something was is good for show, but hackers are often a lot more likely to dwell on how fun their journey was and all the awesome things they saw and learned.
