Why most people identify Math as a difficult subject?

Is really Math a subject exclusive to geniuses?
As far as I am concerned, you don't need to have a very outstanding IQ to do Math.
The human brain is like a sophisticated computer, to deal with a given topic, your brain uploads all the context you need to understand your topic to your working memory. It is true that the working memory capacity differs from one human to another, this why our understandings differ.
The majority of topics require a minimum of information to be uploaded to your context memory, either because every situation is independent or because you are familiar with it .
To illustrate this, I go to my kitchen to cook: my brain uploads to the working memory the places of the ustensiles and ingredients, the cooking methods and processes ...etc
If I read a book of History talking about the French Revolution, my brain situates the span of information toward the 18 th century, and It uploads only the events in this period that will allow me to understand the context of the French Revolution.
Mathematics is different than the majority of topics and the usual situations because you require to upload all what you have studied since the first years of your education to understand a simple equation. You may notice that every lesson of Math you have ever taken requires you to have full understanding of all the previous lessons. Everything in Math is channeled, and sometimes you block at solving a simple Math problem just because some tiny piece of information is missing at some stage of your Math education.
So, if you want to be good with Math, you need more focus while you study or do research, because you will need all your working memory while doing Math. Otherwise, you must have a very exceptional memory : I guess people with such a memory have an easy life , isn't it?

How to be more productive? No nootropics involved!

Yeah ! Another boring topic.
I am a lazy person, and I get bored easily. However , to earn enough money to survive in this world where everyone is working all the day long is not so evident with those qualities (Lazy and easily bored).
So , I was looking around the web for the easiest ways to improve your productivity while investing the least effort .
There are two things important about productivity: Motivation and ordering Priorities.
1-Motivation
 Keeping up motivation is difficult especially with tasks that require long time to show up results. In order to keep it up all the time, you need to set up some macro goals! Yeah , you read it right: The Sky is not even a limit (I will send a rocket to space, I will build a Villa on the Moon....). These macro goals -no matter how they are- are feasible! These goals are your fuel to wake you up in the morning. However; keep in mind that to attain those goals , you need planning and setting up milestones. For example, I am now a simple Biostatistician and PhD student, I want to launch a Rocket to space.  I need to mark milestones: Get noticed in the scientific community with some substantial contribution, build a private research facility in my country that will facilitate jumping up to space. Then to reach those goals , I need detailed plans: what resources do I have? how I will get the ressources I need ? Who should I get in touch with?... The answers to the right questions are your master plan. Then We get to the stage  of micro planning: Everyday you commit to get something done, so you are one step closer to your Ultimate goals.
2-Ordering priorities
If you have too many interests: you will tend to get distracted all the time and lower up your abilities to get anything done. You need to pick like 5 things at most to work on, like :
 1-I will work hard to get published
 2-I will make savings to enroll in an executive MBA
 3-I will volunteer to Rethinking the educational system in my country.
 4-I will practice to be a prima dancer
 5-I will work to perfect my German and Hebrew.

The rest of my priority list can extend to more than hundred (6-Finalize and publish my Novel, 7-Write a new book, 8-Adopt a kid, 9-Get an Olympic Medal in Taekwondo, 10-Build a private laboratory for my personal use, 11-....., 101-Build a time machine, .....1001-Be a polar bear....)
Ordering priorities within time spans is the key to avoid distractions. You have 24 hours a day: I personally sleep like 7 hours and a half , I spend 10 hours at work and going coming from work and getting ready to go to work. I spend an hour preparing and eating dinner. I practice for an hour. I read or try to solve some equations for like 3 hours then  either I watch something or play games before I sleep. During the weekends I have more time for further work on my priorities and have more fun.

To sum up: Have fun working toward your goals ,
                   Avoid distractions
                   Get organized
                   Don't work hard, be smart!
Daniel Goleman said : Productivity is all about focus. So my dear friend, don't get distracted.
