At this point you don’t need anyone to tell you about the benefits of safe guarding your seed phrase, if you feel your security is not so good why not create another alternative. After reading this I’m curious to ask if anyone can actually memorize their seed phrase for a long period of time without forgetting the words, it’s obvious the brain works differently from other body parts so I will advice you avoid such move. We’ve clearly seen people loss their memory at an old age or due to certain reason besides I can’t just memorize my seed phrase without other alternative rather I will not feel alright, it all depends maybe yours is so different.
