First: There is a certain amount of time you have to dedicate to a task to complete it. Estimate that amount of time, estimate how much time you actually have left to do it, and adjust the goal or deadline if necessary. This avoids the classic "huh maybe I'll do it this weekend or whenever I feel like it" proceeds to not do anything for a month.
Second: Writing stuff down on a physical piece of paper is valuable. I'm sure this doesn't apply for all people, but I believe having all of your notes/tasks/ect. on a computer screen is not the most optimal for our brains to process.
You not only have the abstraction of the current task, but also you're viewing it through a small 13 inch window on a generic document that sits somewhere on the abstract device called "your computer" or "your cloud". All of that information sits in your mind and takes up cognitive power from other tasks.
This is why I think writing stuff down is useful - it's making use of all of your other senses, which are subconscious. The things you write are unique. They have their own physical weight, their own look and mood reflected in your handwriting, they're located in a certain space on your desk or drawer, or maybe you scribbled a random picture on it.
Your brain automatically remembers these random details and helps you organize them. When you're looking for a note or document it's much easier to go to a physical place and say "there!" than to browse folders or websites on a computer.
Poland:
If I'm sick or it's the 1st step in getting something diagnosed: I call the (public) clinic to book an appointment, get a date within like 3 days max. I usually leave with a prescription and paid doctor's leave for work. The visit costs nothing. If it's urgent you can walk in without an appointment or call the ambulance/go to the ER in your local hospital. This is free.
Sometimes the doctor gives you a medical referral to a specialist or for a certain test. This can be realized in the public health system, or at a private clinic.
Wait times vary a lot - some things like a blood test are very quick, but some specialists in the public system have very long wait times. Like, 6 months to a year. Some surgeries in the public system can take even longer. The public system is free, or has a small symbolic fee.
The private system is much faster for certain specialists - dentists, psychologists, dermatologists, injury rehabilitation, ect. but it also can't do everything. In my experience, almost all serious and niche surgeries are done in the public system for example.
Overall it's a decent experience, but the system is severely underfunded. This isn't really a case of mismanagement imo, it's genuinely just a lack of money in the system. Some surgeries can get delayed because money allocated for them ran out for the year.
