I like how you put forth a routine, so I'd like to postulate some ways to modify it with future advances in the next 50 years (hypothetical, but optimism is great):

Waking Up and Sleep go together: Neural implants that reduce the amount of sleep needed drastically by stimulating the brain into REM sleep immediately, or by outright replacing parts of the brain (or body) that need the recuperation time. I don't think it will be healthy for a while to avoid sleep (unless you replace a significant portion of the human body or endocrine system), but we should be much better at letting people do it.

Work: Since we are moving to post-scarcity, I easily see us having automated transportation of goods, automated farming (or even better, molecular printing that fabricates food from carbon and friends), automated mining - and we should be able to easily automate construction to just taking an input design and having a machine crew do the work. Robots that can maintain their peers and themselves, communicating their defects so they can be serviced. No human involvement. People could then commit themselves to either constant leisure, artistic pursuits, or the sciences, and only if they want to, since they would no longer have to.

Eat: Soylent and its ilk are even right now aiming to change this, and if the above considerations happen, you don't need to work to feed yourself, and can print any food you want. Though it will be some time before humans start replacing their digestive tract with 3d fabricators so they just plug themselves in to electricity to "eat".

Church: Already dying in the newer generations, due to the pervasiveness of knowledge and freely available information. If anything is the death knell for religion, it is the Internet and its ability to distribute knowledge anywhere instantly. It makes rationalizing the unknown less about guesswork and superstition and more about googling it.

Seek Mates: I think this will be around because human beings are stubborn and set in their ways, but beyond 50 years I expect us to transition away from sexually partnered couples with children to a system where everyone is sterilized and children are grown (with perfect genetics) as needed and raised in public institutions where (through rigorous study) we (collectively) have figured out how to best promote creativity and open minds. It is one of the greatest weaknesses in modern society that because everyone is in their developmental years bound to the behavior of their parents they can have vastly different advantages and disadvantages throughout life.

In the absence of the superficial need to spawn being bound to romantic relationships, I expect people to be more fluid and have sex with various acquaintances. I also have a feeling that, biologically, humans are inherently much more bisexual than anyone wants to admit, and we are culturally driven into a singular sexual preference (usually the straight one - I'm asexual, and I feel it was because I was never pressured into having relationships I didn't want), but I have no idea how true it is. Just an intuition.

Sing Songs: I hope so!

Drink: Would be nice if people weren't so depressed and sad they needed to lose their ability to cognitively reason and lose their ability to recall what is happening.

I'm all for changing the basics. But I agree, we have this culture that is very resilient to change that will take fundamental changes to bend to something more fulfilling for people.
