After a truly terrible day at the office, in a quiet moment of reflection, you might marvel at the fact you had the fortitude to get through the whole experience without screaming (or quitting). You think, “How did I do it?”

A likely factor: You have the character traits of a mentally strong person.

Mental strength can be a road map for personal success in all areas of your life — including your career. But to use your mental strength to its full advantage, you need to focus on developing it just as you would any other high-value skill.

That process includes honing your sense of purpose and cultivating your ability to make good things happen. It also may require refining many of the attributes you already tap into when situations arise that require you to be resilient. Identifying character traits associated with mental strength that you may need to improve or learn is also worthwhile because these qualities can be valuable to you in many ways.

What are examples of strong character traits?

Mentally strong people have many distinguishable character traits. Below are 30 examples collected from or inspired by various articles we found on this topic from sources like Scientific American, Success Magazine and The Huffington Post. With each example, you will find a short explanation of why these traits can be so valuable in your professional life.

1. Tenacious

When faced with a problem, you won’t give up until you find the answer.

2. Confident

Your boss taps you to give the presentation to the firm’s biggest client. Your response: “No sweat!”

3. Optimistic

You’re in line for a promotion but are not the only candidate under consideration. You’re not worried, though — you believe the odds are in your favor.

4. Self-aware

A coworker’s behavior frustrates you. You don’t snap at her. Instead, you think of a measured way to express your annoyance and, hopefully, motivate your colleague not to repeat her actions.

5. Adaptable

You recommend a strategy that is rejected by your project team. You ask your colleagues to help you brainstorm an alternative and ultimately embrace an idea that hadn’t even occurred to you.

6. Flexible

Your firm is implementing a new business system. You commit to learning everything you can, as quickly as you can, about the new technology.

7. Drama-free

You’re known for helping to defuse conflicts at the office, not for creating them.

8. Reliable

Your coworkers know they can count on you. Period.

9. Fair

You always take the time to hear both sides of a story and gather all the facts before making a judgment.

10. Self-sufficient

Teamwork is great, but you have no trouble flying solo when needed.

11. Consistent

To your colleagues, you’re a known quantity, not a question mark.

12. Hard worker

No one would ever associate the term “slacker” with you.

13. Takes responsibility

When you make a misstep, you own it.

14. Understands that life is not always fair

OK, so you didn’t get the promotion you were so optimistic about. C’est la vie – now, onto preparing for the next opportunity!

15. Welcomes a challenge

A new and potentially tricky assignment? Sign you up.

16. In control of their actions and emotions

You never have, and likely never will, embarrass yourself at the holiday office party or any other company event.

17. Embraces change

Your firm is in transition. Instead of fearing what’s ahead, you make a point to find out as much as you can about the change and offer your support to management.

18. Unafraid to speak up

Your boss asks for your opinion about a proposed process change. You don’t hesitate to provide it — and suggest a different approach.

19. Navigates upsets with grace

That promotion you didn’t get? You sincerely congratulated the person who did.

20. Celebrates others’ success

21. Willing to take calculated risks

Now that you’ve been overlooked for a promotion, it seems like a good time to ask for a raise.

22. Learns from mistakes

Oops, you miscalculated on the raise. Turns out your request was a bit over the top. You’ll be sure to do your research next time.

23. Enjoys social interaction

When coworkers want to go out for coffee, play softball after work or celebrate a colleague’s birthday in the breakroom, you’re more than glad to join in the fun.

24. Values solitude

Sometimes, you prefer to eat lunch alone under a tree.

25. Quick to share credit for good work

Sure, you spearheaded that project. But without the support of your team, you never would have made it to the finish line on time.

26. Committed to long-term goals

When you make a plan, you stick to it.

27. Able to see the “big picture”

You can visualize how your job contributions help the business achieve its broader objectives.

28. Ready for the unexpected

Surprise! The firm just landed three new accounts, and your boss wants you to manage them all. You ask, “When can I get started?”

29. Manages stress effectively

Sometimes, work is pretty intense — but you always do what it takes to maintain work-life balance, so you don’t burn out.

30. Prioritizes health and well-being

You understand there is a connection between your mental strength and your overall wellness. That’s why you never let your health and well-being take a backseat to your job.

How many of these character traits do you have? Many are the types of attributes that are the mark of a good leader and examples of the nontechnical skills that many employers look for in today’s professionals. So, they’re worth developing not only as part of your quest to build your mental strength but also to help advance your career.
