Check your Seed twice. Do not be lazy.
This is a simple and yet very important reminders for people who wanted to or prefer to jot down their seed phrase in a paper than saving it on a notepad. Although I don't use this method since I am using electrum, I can copy it on a notepad and print it on a paper if I wanted to save a back up of the seed phrase outside my computer. Aside from that I always get the private key of the address I used for receiving and then import it to just have a solo address for receiving(this is to prevent remaining BTC to be sent to other address when transacting part of the BTC held on that address). This way I have two options in recovering the address, one is through the seed phrase and the other one is through the private key.
