Eren is the new generation, the one who lost their home and familly due to the attack. It's only natural some people from that generation will have more guts/motivation to train properly and fight the giants. It's also true for trainers, science and technology effort.
After 100 years being lazy, Mankind remembered they have to move their asses for survival, that attack reminded them of that fact.
