Fun fact: Nordic countries use week numbers for all sorts of planning, e.g. vacation period, school events, company planning, statistics reporting, ...
All calendars show week numbers.

I am also a big fan of setting yearly goals. Been doing this for a couple of years now. This has sort of converged into a tradition of having ~12 goals per year.
Each item is something quantifiable and achievable. For example, a goal of mine is 'losing x amount of weight', as opposed to 'becoming fit' - this I won't expand into other domains however, if the context is making a game, it would be 'publishing a game', and not 'publishing a game that sells a million copies', as the latter depends on factors outside of your control, luck, etc.
The way I set up my own goals, they are achievable if I were to focus on these for a quarter alone. They are not big, huge deals. But I don't focus on these for a quarter of course, I have to go to work, and I have a family and loved ones that I enjoy spending time with. Yet it is also an anchor I look at occasionally, and if the list is having too little progress, I get the message that I should work on these for a while. I find it to be a nice balance.

Just make sure to turn on week number in your calendar applications, then it might be more useful to you.
Yet another fun fact: with %V week numbers, the date 2024-12-30 (December 30, 2024) was 2025-W01-1 (the Monday of week 1, 2025). Thus strftime needs two different ways to specify the year: %G denotes the year that goes with %V week numbers, %Y denotes the year that people usually think of when they ask "what year is it". Unfortunately %G comes before %Y on the strftime man page, so people who scan the page quickly can easily pick %G when they really want %Y. I've seen a few bugs caused by this.
I have also seen the corresponding bug in SQL, using IYYY instead of YYYY. This boggles the mind, but apparently when some people read "ISO 8601 week-numbering year", they only see "ISO 8601 ... year", think "yes, that's the date standard we use" and don't care about the "week-numbering" word in the middle.
I've done a bunch of thinking around how to organize things in dates, etc, and often wondered if I should be using week numbers. Never thought to look up if it's a common practice in any countries.
(You can activate week numbers in Office Outlook as well. Or go to ukenummer.no for simple display)
