5 principles, laws and rules you should know about.

Check out today’s Teatime Titbit: 5 principles, laws and rules you should know about.

We are surrounded by and affected by rules & laws – for good or for bad. Here are 5, which are pretty handy life hacks:

‘Pareto – 80/20 principle’ states that 80% of the results come from just 20% of the work. Great life hack so long as you can put your finger on what the 20% is.

‘Parkinson’s law’ states that work will always take as long as the time available for it. Check out this great article on how to take advantage of this.


‘Rule of three’.

I first came across this when I attended a ‘Presentation Seminar’ by Hawkins Consulting (www.hawkins-consulting.com) and was introduced to it. The idea being that words/ideas often come in groups of three & as such seem somehow more powerful & are easier to remember. It crops up (auftauchen) everywhere (once you know about it) like in speech writing/ marketing etc

E.G. the ‘rule of three’ in (olympic) sport = bronze, silver, gold or in history ‘Veni, vidi, vici’ or more info: http://sixminutes.dlugan.com/rule-of-three-speeches-public-speaking/

A ‘rule of thumb’ is a practical method of doing or measuring something, usually based on past experience rather than on exact measurement.

‘Murphy’s or Sod’s law’.

On a slightly less serious note, there’s always ‘Murphy’s law’ or the more colourfully named ‘Sod’s law’, which both basically mean that ‘whatever can go wrong, will go wrong’. According to (Laut) Wikipedia https://en.wikipedia.org/wiki/Sod%27s_law ‘Sod’s law’ is used in the UK, though in North America “Murphy’s law” is more popular.

Thanks for sharing!

Also worth mentioning is “The rule of 10” which describes that the later a mistake/problem is discovered during product or process development, the more it costs to rectify it. From stage to stage the costs multiply by 10.

There are a lot of rules out there, we could go on endlessly. However, there’s one more rule I like to refer to because it is so important nowadays – the “20-20-20 rule”: every 20 minutes you should take your eyes off your laptop/cellphone display and look for 20 seconds at a point that’s 20 meters away – thus, your eyes can relax and you might prevent short-sightedness.
