Private keys and Seed phrases are like your whole life in crypto, if you mess with it, you're gone. Protect it just the way you protect your self. In life you won't go to places that are harmful to you, or a place where you are not comfortable. That's how the private keys and Seed phrases are in this digital asset. Do not keep in any how, you must store it in a place where only you can acces. Never be careless with it, because if a third party see it, they can access your account and withdraw your portfolio from your wallet. Value it the way you value your life, as a beginner the first thing you should be conscious of is how to protect and keep your secrets passwords before you can buy any digital assets.
In the past have lost assets because of my carelessness, till date I lost the wallet,I can't find where I wrote my wallet passwords and I didn't share it with my trusted brother. Have learnt my lesson, I share my secret seeds with my brother even when it's against the rules. I still find trust in him, if you have a trusted ally you can as well share it with him in case of tomorrow.
I also think so, I consider Private keys or Seed phrases to be my lifeblood, it might seem strange to some people, but for me, it is real. Imagine if we lost or had our crypto assets, or especially the Bitcoin we own and have saved up was stolen, so we would likely lose our passion for life, or even decide to take our own lives (sorry for that). Furthermore, we can see some news stories regarding this, which could potentially threaten someone life, such as robberies, kidnappings, torture, and even murders (we can find them through search engines or browsers). Therefore, cherish these keys for the safety of our life by protecting them as best as possible.
