"By the way, (American) English is a very flexible and tolerate language..."
Sure, but that sentence immediately marks you as a second-rate English speaker. Many will take that as a reason to doubt your thoroughness in other areas.
There is no excuse in not learning to speak and write properly in spite of the fact that for many of us, English is not our first language. And we should try the best we could to make up the difference but it is just one more thing that we have to overcome in our journey as struggling entrepreneurs. But interestingly, my personal experience is that it wasn't until I learn to stutter and I learn to take notes that I start to succeed in startups.
In general, people are suspicious of perfection. You have to show flaws or they won't stop looking for them. I actually had better luck when I don't act perfect. "Strategic Stuttering" turns out to be an important skill.
Also, people don't understand that I have perfect recall (not perfect memory, just perfect recall) and they think that I am not paying attention when I am not taking notes. So I take notes and now everyone seem much happier.
