Ultimatum

1. Granularity -
If a topic is too hard for you, learn to break them down in smaller bite size information which is easier to comprehend. Almost all complex topics are made up of lesser complex subtopics and again these subtopics can be broken down to even less complex subtopics and so on and so forth. Think of it as food recipe which is divided into ingredients and procedures.
Example: In art, it would be way easier for artists to draw a human figure in a scene properly using only imagination if they know fundamentals of human anatomy and perspective. In science, you cant simply tackle physics if you dont know your math fundamentals. Math fundamentals itself can be broken down to smaller topics, etc

2. Comfort zones -
Create comfort zones where you excel and slowly conquer nearby zones. Just like mountain climbers have "base camps" so they can rest and prepare for the next challenge. Comfort zones are considered "easiest" topics for an individual hence the term comfort. Moving from comfort zones to new zones can be a challenge but is easier if its nearby and both zones have a thing in common.
Example: In music, if one knows how to play basic guitar (changing chords fast and clear), what would be the next challenge? adding simple riffs between chords might be a challenge but its way easier if you know to change chords fast enough and in right timing.
In P.E, one hand push ups might look like impossible, but if you're already comfortable with regular push ups, it would be easier and more feasible (not saying its easy) for you than the others who cant do regular ones.

3. Multiple perspective -
Seeing things in multiple perspective will help solidify your understanding of a certain topic. Not just topic in abstract form but even physical dexterity if practiced. The idea is to improve the connection of thoughts by observing it end to end in detail.

Examples:
 In art, most notable example is simply drawing a certain picture of a person or object; instead of just looking at the silhouette of the object to get its shape, you can look at the background shape (or space, simply the things surrounding the object instead of the object itself) as well to further clarify the accuracy of your drawing.

In music, learning how to read sheet music for piano usually starts with identifying what notes are in the piano keys first, then what notes are in the staff. So basically, theres an obvious conversion happening in your mind when you try to play sheet music for the first time:
- identifying the note in the sheet music
- finding that note in the piano
(sheet to piano approach)
which by practice will gradually improve your reading and conversion speed to natural level. But that is just one perspective, another perspective that would help is by using the inverse approach which is (piano to sheet). This is simply done by playing a specific piano key then "wondering" how it is displayed in the music sheet. This way, you'll have a more solid view of how notes are connected between sheets and the keys.

In math, solving a particular problem using another equation other than the standard one is a good way of solidifying your comprehension of the topic. e.g polynomials which can be solved using foil method, pascal's triangle and binomial theorem, what are the differences between them and how they solve it? why are polynomials can be solved by those 3 methods but not with the others? These are just sample questions that if answered will surely enhance one's understanding of the topic because of different perspectives.

4. Combining concepts - We know granularity talks about breaking down of complex topics to understand a topic easier but "combining concepts" is more of an inverse concept. We combine concepts in order to "speed up" learning of different fields. This is achieved when the field is vast and can be applied to anything (e.g: programming, business, mathematics, language, etc). Good example would be learning how to program and learning a new language. Programming "something" like a pet project in order to learn how to program is the best way to learn programming because it's a hands-on process. But every pet project can have a topic like learning a new language or subject etc, which is part of the project theme or concept. Instead of programming something just for the sake of programming, why not create a software out of programming to learn other topics effectively? If executed properly, you are hitting two if not more birds using a single stone!
