I agree with this.
1) spending a few extra seconds to ensure clarity on conclusion before jumping into analysis - very useful. I strongly emphasize this.
2) taking a few seconds trying to figure out what can work, analysis free from the boss of anser choices - has helped me with a lot of questions. Esp for easy, medium. But also for quite a few hard ones.
3) in some cases, nothing clicks at that point, which is ok. The choices are there anyway. In general, I have found the exercise useful. But it takes some getting used to.
4) You will see both sides. For some, the above works. For some, it doesn’t. In any case, it needs some time and practice to get used to.
