Mike I was about to say that I could tell you are very creative and then you mentioned that you were a designer.  How cool!  With your permission I will just make a few adjustments below.  I hope they help you along.  I enjoyed reading your entry. If you have any questions in general or about my comments feel free to ask.  Good luck with your studies!

Why I learn English.

Today l listened [to] music, read [the] news, watched TV and so on...But it was English music, English news, English movies. English [is all] around my life. Every side [of] my life is connected with English. I am [a] designer and most new information about my profession [is] written in English.
And once I said: "If I learn English i will be another person. I will be better - more smarter, more beautiful (inside) and etc."
If you study some language - you will be better. I believe in it. Never give up. You can speak English.
It's time for the next idiom. Today it is "Ничего страшного". Maybe it isn't idiom but Russian people use this phrase very often. Translate word to word 'Nothing terrible" is not correct in English. In English it may mean "Okey", "Don't worry", "Never mind" and other. For example:
- What is number our class?
- Six, but it still busy.
НИЧЕГО СТРАШНОГО, I'll wait.

I did not fully comprehend your example, but I think I understand the meaning behind the phrase or "idiom" as you described.  It seems "Ничего страшного" means "It's OK."  Yes?
