The 10 Essentials illustration: a list of essential bits of kit for camping and being out in wilderness is laid out; compass & map, hat and sun cream, a warm jacket, head-torch, first-aid kit, lit match, tape & knife, food and snacks, full water bottles, a tent or tarpaulin.

The 10 Essentials

What should you make sure you have with you when you head out to the wilderness? A lot of stuff may prove handy, but perhaps the best checklist to start from for stuff that may get you out of a fix is the 10 Essentials by the Seattle-based Mountaineers group. This is a version of their systems list which focuses on what the objects need to do rather than specifically which objects you should bring. So, for example, insulation may be warm clothes but could be a wind breaker or waterproofs for snow or rain rather than cold. Check out Mountaineering: The Freedom of the Hills PS I modified it very slightly for space and simplicity. Don’t blame me if you are stuck in the wilderness without the right kit.

How to remember if you did something illustration: a person does a star jump as they leave the house and lock the front door. Later on, remembering that they did a star jump helps remember that they locked the door.

How to remember if you did something

A simple way to remember if you locked your car, turned the gas off, watered the plants or whatever, is to do something unusual around the time that you do it. When you find yourself thinking back to whether you did it or not, you will know for sure when you remember the strange thing that you did that is connected to it. The only limit is your imagination. Ironically, I can’t remember where I learned this — I must not have followed this tip.

Johari Window model illustrating self-awareness through feedback and disclosure in four quadrants: Open Self, Blind Spot, Hidden Self, and Unknown Self.

Johari Window — A Model for Self-Awareness, Feedback, and Personal Growth

The Johari Window is a model for understanding self-awareness and improving relationships through feedback and sharing. It divides what we know about ourselves—and what others know about us—into four quadrants: 1. Open Self – Things you and others know about you. 2. Blind Spot – Things others see about you, but you don't. 3. Hidden Self – Things you know but choose not to share. 4. Unknown Self – Things about you that neither you nor others know. Most people won't be aware of much that you know about yourself —through sharing or disclosure, you help others understand more about you.  Conversely, some aspects of yourself are invisible to you, and only others can see them clearly—you need to receive feedback to learn about these. Over time, this process can lead to deeper self-awareness and personal growth. Other aspects of yourself, especially when you are young, may remain buried in your unconscious mind and are thus unknown to you and others. The size of each quadrant varies in different relationships. If you join a new team at work, your hidden self may be large since colleagues don't yet know much about you—there will be a lot you need to share with your colleagues to help them understand you better. In contrast, your oldest friends may know how you'll act before you do yourself. The Johari Window is widely used in team development, personal reflection, and communication training. It helps build trust, improve feedback culture, and uncover hidden strengths or challenges.

The name "Johari" comes from a combination of their first names—"Hi, Jo, Harry!". Today, the model is a well-known tool in psychology, leadership training, and self-improvement. Nicola Rowledge shared the examples in the quadrants with me.

Santo Libre & Cuba Libre illustration: a dark drink on the left is a Cuba Libre (rum & coke). A clear drink on the right is a Santo Libre (rum & lemonade)

Santo libre, cuba libre

I first had a santo libre in Belize and, given how popular cuba libres are, I was surprised I’d never heard of it. Basically, it’s rum + Sprite or lemonade + a little lime juice. I am hereby spreading the word of this excellent drink.

Wrap up your keys for running: a set of keys on a keyring are wrapped up in a small piece of clingfilm. The when the key owner goes out running, they have a smile on their face as there's no jingling coming from their pocket.

Wrap up your keys for running

You often need to take a house key with you when you go running, yet if you pop the keys in your pockets, they often jingle as you run. I've often thought it would be nice if they were quiet. How do you stop your keys from jingling when you run? A handy tip is to wrap your keys in cling film or Saran Wrap. This instantly stops the clinking, allowing you to run jingle-free. I learned this from James McManus. Also see: Fartlek, Run further by running far away, London running kit
