Go to a photography forum and most of the discussion is usually about cameras. Hang out with motorcyclists and most of the discussion is about bikes. And I’d venture to say that in a samurai dojo, there was a great deal of talk about swords.
Likewise, in groups of people learning languages, the dominant topic is tools: which books, or no books at all; whether to SRS or not; what style of SRS cards; immersion versus intensive study; dictionaries, programs, apps, and on and on.
It could be considered that all this is much of a waste of time. The true expert thinks about his practise and his technique, and not much about whether the camera or motorcycle or sword he is currently using couldn’t perhaps be replaced by a better model, or upgraded somehow. However, I can’t say I fully agree with this. How many of us are at that level? How long did it take Kiyonari to master the track, or Musashi to master swordsmanship, and how much experimentation with the equipment took place before it ceased to be a consideration?
There’s one sword that fits you and only you perfectly. Don’t get attached to the old ones, and don’t be afraid to try new ones, until you find it.
