“I don’t know” attitude is a healthy attitude to maintain in problem solving.

The idea is : though we don’t know the solution the solution is already hidden in the problem. We just have to find it.

There are three basic approaches to solving problems, which are as follows:

1. If you start out intuitively you need analytical thinking to confirm your learning.

2. If you start out analytically then you need intuition to tell you “what next?”

3. If you start out with imagination then you need a prototype to confirm your understanding.
