I was a little nervous when I stood behind the technician watching, but I felt relaxed after a successful puncture. "It's not as hard as I thought." I murmured. But luckiness was not always with me. I failed on the 4th patient. Thanks to the technician. She took over the needle and didn't make the patient angry about my fault. I didn't feel much depressed. I knew before I become skilled, I must experience a lot of failure.
On Tuesday, I totally punctured about 15 to 20 patients. Tomorrow I will have another chance. Hope I could do better. This is a good news for both the patient and I. :p
