I don't think the failure to answer the above questions is directly related to understanding or IQ.

Improving workplace understanding: can you see the essence of the problem through analysis? There is also the subtext, that is, you should consider the multiplicity of tasks given by your boss.

Never mind. You can think more and judge more.

Speak more, read more and write more. Be confident, even if it is wrong, but dare to express clearly. Express the information you want to convey clearly in the most concise language or words. As long as you are confident, just look at your expression. Don't be afraid of right and wrong. Think clearly, or even if you are right, others won't know what you are talking about. How can you talk about right and wrong? You intend to convey clearly and dare to express clearly.

3 improve ... ability ... what is this? Very imaginative. You can only exercise for what you want to improve.

Believe in yourself and be a free and easy person. Thinking about things every day is really hopeless.

Read more books. With more knowledge in all aspects and fields, your thinking will be broadened and your understanding ability will be OK.
