My word is my bond.?

I am very like this quote.? This quote is used for saying that people can trust you because if you promise to do something, you will do it.?

This is what I do. Last year, I am involved in team to translate a course into Chinese. There are 15 team member including me. However, no one can translate it to last except me. I did not mean how I am good. I simply think I promise to translate this course and I should complete it even no one can work with me. I still want to complete it.?

I had hope that my team member will come to work with me. However, ?no one come to work with me in the end. ?I totally spent 7 months to finish this. ?

I still keep my word - My word is my bond.?
