Personally, if I had the choice, I would choose a life that is eternal, nothing but blissful, has no problems or hardships, and has no suffering, illnesses, or diseases. Some people would choose a hard life filled with hardships since they wish to grow and develop. But some people such as me have absolutely no need for growth, growth does not give any value to our lives, and it is all just pointless misery and turmoil for us. I will give you an analogue for how a blissful life that has no hardships is the better solution:
Imagine a patient has cancer and science already has the cure right there. Should this person just suffer in agony until he/she goes into remission from his/her cancer one day? Or should he/she just take the cure right now? Obviously, the solution here is to take that cure. It is pointless, in my opinion, to just choose to suffer in agony. I will give another analogue. Imagine if there are two ways to get somewhere. One way takes a very long time while the other way is a shortcut that will get you there quickly. The better solution is to take the shortcut since the long way is nothing but problems, anger, frustration, and misery.
So there is my analogue. I would apply this analogue to life itself in general. In other words, I am all for better and healthier solutions. I am not at all for a life of hardship and misery. Such a way of life is not only pointless misery, but a waste of my time. Therefore, my attitude is that of a future civilization. Imagine what types of people we will be later on thousands of years from now into the future.
If we have found cures for all suffering and illnesses, then our attitudes would be very likely similar to mine. We would see hardships and suffering as pointless misery since science has finally found the better solution which would be cures to give more quality, more happiness, and a life of freedom to us as human beings. So that is my attitude towards life. I would like to hear what others think. Besides, there are other ways to grow besides hardships and suffering. You can grow through a blissful life instead.
Lastly, I would never grow bored or tired of an eternal blissful life. The only way that could happen to me is if I develop a need for a life of hardship and misery. That is how we as human beings grow bored after all. We grow tired of a certain thing for a while and we need something else. But since I will never have a need for hardships and suffering in my life since it is all pointless misery that has no value to me, then that is why I would never grow bored from an eternal blissful life.
I still don't agree with that. Everything would have far more value to me in an eternal blissful life since I would be free from all suffering, death, depression, anhedonia, and illness which are depressing restrictions put upon my life. This sense of freedom would motivate and inspire me to do more and more in my life. It is no different than how a wild animal is locked up in a room or a cage.
This animal would feel depressed and wouldn't be as motivated since the animal is restricted from its wild and free, happy, blissful environment. But if this animal were to be set free, then it would have all the happiness and motivation in the world. Its life would be far more valuable set free in the wild than locked up in that room or cage.
