One facet of the problem is when you replace the word others by yourself. Did it ever happen to you that you find a nice construction, a nice concept, a nice property, giving you a research paper of which you are proud ? Once the exciting period of intensive research ends, you come back and ask yourselves How did I come to find this trick ? Why did I look in this direction ? And sometimes, you just cannot remember How and When. But you did it !! If you can't explain yourself this process, do you expect to explain others we way you think ?
