I think a lot of "inner confidence" comes from personal experience. I was watching a documentary about the French Foreign Legion in which a group of average guys were put through a month's rigorous training. The FFL is renowned across the globe for being one of the toughest military outfits, and many of the guys dropped out of the training along the way. Those that managed to complete it though, notably said that "once you've done what we've done, you get a different perspective on what is difficult and impossible". Or something along those lines.
I think if you've already been through tough situations, and had other people helping to push you there in the first place, if you come across another situation that is tough you can dig deep and persevere more so than those who haven't had such experience.
I guess that's one reason for why some people seem to be able to push themselves more than others.
