Notes extend our memories and enhance our focus. But before building a note-taking system, or taking notes, one should be clear of the purpose of notes.


Decide whether to optimise for review or retrieval practice.


For docs you don’t plan to study extensively, the review is the obvious choice.
For texts you need to master perfectly, the Question Book Method (for theory) or flashcards (for details) saves time.


When you want to take notes to read them for pleasure afterwards, highlighting and marginalia could be more suited. But if rediscovery is your desire, a structured system, such as an index of the critical ideas, maybe better.

CTA or Call to action is a marketing term for any device designed to prompt an immediate response or encourage a quick sale.
The three key metrics to measure for each CTA are:

Click-through rate: a measure of what portion of the people who see your CTA, on your blog, in an email or social media — click on it.

Clicks to submission: Of those who click on the CTA to reach a landing page, how many submit  the landing page form and enter your lead nurturing program?

Views to submission: What percentage of people who see a CTA end up converting into a lead?

The MECE principle suggests that to understand and fix  any large problem, you need to understand your options by sorting them  into categories that are:

Mutually Exclusive – Items can only fit into one category at a time and

Collectively Exhaustive – All items can fit into one of the categories.
MECE  helps to break down the complex problem into smaller, non-overlapping  units which overall constitutes the complete problem. We can then proceed with the analysis of the individual subproblems and further apply MECE if possible.

Merely acquiring information is not learning. Learning is a two-step process:


Read or listen: feeding ourselves new information.
Process and recall: connecting new materials to what we already knew.


Our focus should be on understanding the bigger picture, on how things relate to each other.


There  are many ways to learn effectively, and it boils down to our personal preferences. This can be either by mind mapping, or active recall, or  teaching others, or any combination of these and other techniques.

Principle: Churn rate measures how much an old customer is engaged with the business. This is different from the growth rate, which measures the scale at which the business grows.
Situation: High churn rate signifies that old customers are now not using the product or service. Growth rate focuses on the new customer segment.
Note: Generally speaking, the churn rate should be used when a business has reached maturity in terms of its feature delivery. For a young business or feature, growth rate proves to be a worthy metric to track.

Principle: "Work smarter". There’s a lot  of data and factors out there relating to your problem, and a lot of analyses you could do. Ignore most of them. Focus on the most important ones — the key drivers.
Situation: 80 per cent of sales will come from 20 per cent of your sales force; 20 per cent of a  job will take up 80 per cent of the time; 20 per cent of the population controls 80 per cent of the wealth.
Note: It doesn’t always work (sometimes the bread falls butter-side up). Not to forget, numbers "80" and "20" just represent "big" and "small" analogy!
