This is what my Mathematics Lecturer told us years ago when we had trouble understanding why some approaches worked for some problems, but not others. "You need a few more years of study before you can fully understand. But! You have a 600 page textbook. Do every exercise in that book. When you can do that without assistance, get another 600 page textbook and repeat." He was trying to get us to build an intuition for certain class problem solving, while at the same time saying "Shut up and calculate". I find that problem-solving in the programming space is the same. Just keep doing things. You'll develop an intuition for it eventually.
