If you want to succeed in your career, you have to take ownership of both your triumphs and your failures.
Celebrate your triumphs, analyze them, and learn how you can emulate them and build on them in the future.
You need to take ownership of your failures as well, accepting responsibility for them without letting them drag you down and learning everything that you can from the mistakes you make.
Many times, failure is a much more effective teacher than success, and most if not all of the world’s most successful people would not be where they are today if they did not accept their mistakes and learn from them.
