I have a soft question.
I am currently finishing up my second year in undergraduate mathematics. When I look at the "unanswered" section here on the MSE, I seldom understand the questions being asked.
In general, I feel way behind other university students, especially those from other countries. In the US, our standard public education is quite brutal for mathematics.
What can I do to feel more prepared and begin to think like a mathematician? I seem to work hard instead of smart. In other words, I generally lack creativity and ingenuity in solving problems.
