Last Friday, i end my part-time job. It's so tirable to persuade freshman to book <21st century>.

 When it end, i draw a conclude on me . i recongnize that i did't do my best. On the other hand,

i lose my confidence and haven't insist on doing.

 i am diappointed with me. i have no idea why i will give up, maybe i try many times but don't succeed.

 Nevetheless, i should screw up and decide to do better next time.
