Onions turn sweet if you give them time on low heat. Some ideas need slow heat before they make sense.

Low heat does something high heat cannot: it gives a slow reaction the time it needs rather than forcing a fast one. Understanding has the same requirement. Some ideas will not yield to a hard push on a Sunday night, and need repeated unhurried contact over a couple of weeks before they turn into something you can use.

Pick the topic that has beaten you twice and stop attacking it in long sessions. Twenty minutes every other day, same pages, no pressure to finish. Give it two weeks before you decide whether it is working.
