Every example below leads with proof: a title, a real number, and the skills behind it. Find the situation closest to yours, take the structure, and swap in your own detail.
Experienced professional
One clear achievement, stated plainly, does more work than three adjectives.
Manager
Scope first: team size, budget, or territory. The achievement proves the scope was earned.
Career changer
Name what carries across explicitly. A summary for a career change still leads with proof, not intent.
Recent graduate
Little history is not the same as no evidence. An internship, a project, or a GPA all count as proof.
Returning to work
State the break in one clause and move straight to the track record. No apology needed.
