The idea of IQ.

In the foundation, the skill is problem-solving. whether it is puzzle or real life scenario

So you have given a problem, for example, the pet move. So the first thing is going to be, first thing you are in or you are repulse.

Then there has to be a clear comprehension of the problem. You are not confused about the problem but clearly understands it.

Distraction and ego become to obstacles. There is a sense of irritation and aversion to not being proved fool.

The ideal way to solve the problem is to break down in smaller problem if it is possible like TDD. and focus on first chunk. With practice we can learn to see the problem in right light.

One of the worst approach could be trying to solve the whole problem in once.

Another road block we hit is the lack of the knowledge. To solve a perticular type of problem, you need to know the tool relevent to that problem. The better understanding you have of smaller tool, the bigger problem becomes easy. Than you kind of grow in terms of solving that particular kind of problem.

So how come some people are able to solve it faster and some people are not.

You can learn the tools by yourself or you can employ the other people with experties in that tool.

Then the problem solving is nothing but how can you connect these two dots creatively, Or patternwise,

Strategically, you need to understand different paths and their outcome and compare and choose the right ones.

creatively you come up with different path by connecting different points. creatively you are just clearly know your problem statement and sit and ask the questions.

stratigically you have all the tools to organize the information better and take the best course of action.
