Ezra 7 - the man and his renown

In this chapter, Ezra was introduced for the first time in the Bible:

• a scribe skilled in the Law of Moses, v.6;
• the priest, the scribe, a man learned in matters of the commandments of the LORD and his statutes for Israel, v.11;
• the priest, the scribe of the Law of the God of heaven, vv.12, 21.

Ezra also went to Jerusalem for he "had set his heart to study the Law of the LORD and to do it and to teach his statutes and rules in Israel," v.10.
It seems unlikely that Ezra could have written these ascriptions about himself (quaere, what does this question do for the authorship of the book of Ezra?) so Ezra must have truly earned the reputation that even the king of Persia wrote about.
How might I aspire to be like him, not in order to be praised by people, but to be accountable as a Bible student?
