Practice_Drawing

I have been keeping drawing whatever since last week.  I drew those drawings in a coffee shop. I went to the coffee shop where was close to my home. I sat on a chair and tried to concentrate on my drawing. Usually, most of coffee shops is just somewhat noisy. However, it was difficult to practice for me to draw anything home because there is too much of temptation, so I chose to go to the coffee shop. But it was also hard for me to adapt to drawing anything around people who might see my drawings. I felt shy about that situation, yet I did. I drew those things and I thought I need more confidence. No matter what I feel shy about showing my drawings it is okay to draw whatever in a coffee shop. Why should I feel shy about the situation to be able for somebody to see my drawings?
