Amateur radio (HAM) motivated me to go hiking / walking to mountains.
So, I visited e.g. Sněžka mountain, the highest Czech mountain, after approximately 20 years. And other places.

.

I increased my personal achievements in contact distance:

- Unlicensed band PMR 446 MHz 0.5 W: 242 km
(You only need a standard walkie talkie from a supermarket, and some hill in Czechia or Slovakia or nearby with a good view, and you can start PMR DX hobby in the nearest weekend to try to make a contact for distance about 100 km. Yes, using that PMR radio with typical range about 2 km.)

- Licensed amateur radio (HAM) 433 MHz FM, 5 W, handheld: 279 km

(Yes, lot of other operators achieved longer distances,
but I increased my personal records, and it gives me joy.)

.

Thanks to the new collector programme Towers on the Air I achieved my first HAM collector diploma.
I have visited new places in nature in my surroundings, thanks to above mentioned.

(
Unlicensed PMR DX or licensed HAM radio motivates to hike, to make trips into country;
similarly how geocaching can do so.
Basically, someone have to like walking in a country, in nature, to do so;
but amateur radio activities can motivate to do it specifically tomorrow, not "maybe some another day in future".

I started with cold water training.

(
It took me approximately 20 years of step by step getting used to cold water in shower to get myself to level of whole-body cold shower, I achieved it in December 2024, about +10 °C as a coldest water available in water pipes.
I joined a group of winter swimmers going to a swimming pool in October 2025;
I had my first experience with water in the swimming pool containing an ice in December 2025.
)

Air temperature:
Minus 19 °C

Water temperature:
Constant approximately +0 to +1 °C during a frost.

I stood in the water for about 1 or 2 minutes,
other ones approximately twice longer.
(I am still quite a beginner; and good feeling with healthy and sensible approach is the aim.)

.

Warning:
Cold exposure training (winter swimming) is addictive.
Maybe even more than a kickbike scooter.
If you try it, you have to repeat it again and again.
It causes very intensive release of endorphins, hormones of happiness. The body obviously reports that this is very desirable activity (similarly as kickbike scooter riding).


(But, well, ... I have pleasant temperature approximately +24 to +28 °C in the room when I am writing this;
I still prefer rather higher temperature for sitting on a chair in an interior.)

This is a list of main successes only; some things did not go well, of course, but it is not topic of this post.
Remember that no one is 100% successful in anything. Social networks, internet generally and any public presentation in general usually show biased view, preferring successes, and hiding failures or troubles in secret.
There are many failures, problems, issues or partial successes/failures behind and beside any success.
