Yes you can get benefits from CHOSEN and WANTED during a lockdown.
But the more difficult question is whether wanting to change the stack is the right thing to do and possibly influenced by real need OR whether it is reconciliation.
Unfortunately, I cannot determine this for you. At various times since starting the Public Preview, I have felt like changing my stack for various reasons. But I know that if I do, I will feel temporarily excited and then I will want to change my stack again for some other reason.
The best way to solve this problem is to choose your stack after putting in a lot of thought into what you really want or need. And not change your goals until you have achieved them.
For example, I am running Ultimate Artist to get some inspiration in writing and self-discipline. It has yet to show awe inspiring results but I know it is working on me, slow and sure. If I wanted just creativity, I would have chosen Renaissance Man, and boy was I extremely creative when using RM but didn’t have any direction nor discipline nor a desire to monetize my creativity. Which is why I know I should stick to UA for a while instead of falling into the temptation of swapping UA with RM.
So once again, look at what your long term goals are and choose your 3 titles. That way you don’t need to change your stack because there is no change in your long term plans.
