A compact crankset should get you up just about anything and you can achieve most of the gears you would in a triple with a compact. I'm not saying this in any way to criticize your abilities, but just from my own experience (and taking so long to follow this advice that people kept giving me). Any way you slice it, some hills are just tough. They're going to hurt and leave your legs feeling absolutely killed at times. But the more you stick with it, work on your climbing techniques and learn to strike a balance between standing and sitting, you'll become a stronger climber and a stronger rider. More gears don't make you stronger, they just make you slower up hills. Challenge your muscles, realize that some hills will take several tries to get to the top, but commend yourself for getting a little further each time and for getting stronger.
