Do you think about things you thought about last year in the same way you did then? If so then you likely haven’t thought about them since, and perhaps that means that those topics are not so important to you.
Your opinions can and should morph regularly.
Will your ideas automatically get “better”? Perhaps not, but they will evolve in some way, just by the time passing, and the effort you put into them means they’re different. The active consideration matters.
Are you changing your mind, changing the what and the how of what you think, or what you think about? Which is more important?
