If live an eternity, I will have infinite patience. I can ALWAYS play the long game. I never need to settle for something less. This is literally the opposite of what you are saying.
You are probably around 15 right now. And have no problem in living for another x60 years of current age. Why do you think you will feel any different after a thousand years?
Also, you can't die by any means? What will happen if you jump into a black hole?

I already said that all of my friends/family will also be immortal. And, why do you think we should be subjective, and why do you thing I am NOT being subjective.
Why would you get bored, there is so much to do. You could learn all language, go to different planets, read all books, there is literally no end of things to do
Let me tell you what you should do:
Make company
Announce that you have found secret of eternal life
Sell it, but only if they agree to have children responsibly
Profit
