今天学习了三个单词：
Stakeholder
stakeholder 这个词原义为：a person with an interest or concern in something, especially a business. 简单理解是在一件事情上，一个人与它有一定的关联，特别是商业领域。
例子：How can you manage both internal and external stakeholders to drive success and longterm
growth?
Commitment
可以翻译成「决心」、「表态」、「致力于的工作」。public commitment就是「公开表态」的意思。
What does Diablo continuously have to do that defines its commitment to being
customer-centric, earning society’s trust, and building its reputation?
tenure
占有（职位，不动产等）; 占有期; 终身职位;
例子：my four-year tenure as SAP Chief architect
