Unless you have been a victim of writing the wrong word of a Seed down or the incorrect order of it, you do not know how frustrating and desperate such a mistake can make you feel.
I wrote words in the wrong order before and at first glance it looked right. Next time I had to restore my Seed from my paper, it said it was wrong. I got desperate for days, until I tried to swap the word with the previous and luckily it did work for me.
Check your Seed twice. Do not be lazy.
Seed phrase are more critical than the physical wallet; losing your seed phrase means losing access to the coins. Whether you are using options like stainless steel or titanium plates it is important that you check again. In fact when doing this, it shouldn't be at a time when in the day when you are most distracted. It could be in the early hours of the morning or late hours of the night when your mind is more relaxed and your eyes are clear.
