Well, I have to disagree somewhat, with all due respect. I had beliefs like that up until I was at least 50 yrs. old, so I do understand where you are coming from, and I think whatever helps you make it through this stint on the looney bin called earth is great. As a former therapist, I would suggest a visit to an inpatient psych ward, if you want to see people who have been given so much to deal with that they are not stronger, but broken. Catatonics are especially sad to me, curled up in corners, rocking back and forth, hugging themselves, simply unable to deal with the world any longer. I can empathize with that.
I am having a complete nervous breakdown right now, due to undergoing drug withdrawal from a prescribed drug which is killing those who try to go off it, and is said to be the most difficult of all drugs to get off of, combined with a slowly, terminal illness that is shutting down every system in my body and causing me to be homebound and isolated at a time when I have inexplicably become much more extraverted, an unwanted, painful development. The disease I have is known for changing personality as it slowly eats the brain, but I sure did not need this type of change! I just hope my openness helps someone else.
I used to be the strongest person I know, and my childhood friends, who haven't seen me in ages but are the only ones who've stuck with me, even after I listened to doctors who told me to move to the awful place far away from home that I now live in, still think I am super strong, so I do not get the support I need. They keep saying things like "If anybody can do this, it is you" and "you've always been far stronger than I am". That is no longer true, but they still remember me as I was. I am broken and depressed = I need deep rest, but adult responsibilities won't let me off the damn treadmill. Our society makes us ashamed to admit how much we are hurting, so we all hurt in silence, alone, and that is just plain wrong, IMO. It is our society that is so very sick that anyone compassionate may find it intolerable, sooner or later. My own husband says he feels like he is watching me drown but he doesn't know how to swim.
Needless to say, I hope you never end up like this, but it does illustrate that age is not just a number. It can seriously change the point of view for many of us, plus every generation has a collective experience that influences their point of view. I said it would never do that to me, but am now eating my words. I've tried a few friendships with people young enough to be my daughter, but just cannot bridge the huge gaps in things that are perceived so differently. At least I am open to learning new things, unlike most of my old pals. A strong confirmation bias sets in once the brain is done growing, between age 25-35, and it is a rare person who changes significantly after that. One reason so many people are anxious/depressed now, IMO, is that way too much change is being thrown at us for the human brain to handle with it's current hardware. That is a whole other subject to discuss!
To get back to the point of your thread, I agree with @hop-daddy that stress can temporarily kill the creative urge, since I've certainly experienced that. I also have more than 6 hrs. per day of medical chores just to keep going another day, and get too worn out to do anything that is not absolutely necessary. A power failure last fall during a hurricane stopped the intrusion of the outside world for 6 whole days, and was a wonderful respite, so I agree with hop-daddy about vacations and would add that whatever you plan to do when retired....do it NOW, because only 17% are healthy like they thought they'd be at retirement!
