If you want to punish yourself, reciting the seed phrase every morning, evening and night, go on, it's your own cup of tea. However, my advice is that, while you do this, also write down the seed phrase and keep it somewhere very safe. Do not depend solely on your brain as a backup because you may have an accident or sickness that could lead to memory loss and eventually lost of your funds.
You obviously don't read what OP wrote at all, because he also stated that he already write down his recovery seed too, and this is why I don't have problem with him memorising the seed words off head, it is fun actually and I believe that there are some people that are this capable.
The reason why I am against it is because of how unexpected life can be at times, you can have memory losses or get in an accident and lost that very crucial part of your memory.
Since he wrote the seed down he is free to do whatever he wants, and OP if you are reading through this, I want you to know that it's your life and your decision, people don't have to agree to your decision, if mistakes happen you will learn from it. Don't beat yourself hard because some people don't understand you, moreover it's never anyone's money, or assets.
