Question: If I can spare one or two hours daily for my own, what would you suggest to improve my math maturity? I am referring to higher math, not computational math. Here is my little background: I am a HS calculus teacher by profession. Since I picked up graduate math study one year ago, I have been discipline in setting aside at least one hour each day to read and do proofs, especially in abstract algebra since I was told that it is the backbone of all other branches. I do see small improvement in maturity, but I would like to see more. This thread is prompted by @mathwonk 's response to my posting in abstract algebra forum. Thank you very much for your time and suggestion.
