What are your tips for avoiding burnout while maintaining a good reputation?

Just echoing what others have already said in order to reinforce the importance of what they're saying:  set boundaries and communicate clearly.  Most people don't actually want to see you fail (maybe a few do, ignore them to the best of your ability).  Asking for help, talking about being overwhelmed with your managers and peers, and using your vacation to ensure you perform at your best when you're in the office, are all important.  Scheduling time in your day to focus, as opposed to being in meetings, is a great way to make sure you're carving out time for what matters.

Finally, I'll add that cultivating a community (whether online, here, or elsewhere) of likeminded professionals who are empathetic and supportive can truly buoy you during turbulent times.

What I've come to realize is that many people hesitate to say "No" or decline meeting invitations. The truth is, you don't have to attend every meeting, conference, or event that comes your way. This year, my focus is on purpose and adding value. I'm being more mindful of my time, committing to endeavors I can effectively handle, and acknowledging that I don't have to be everywhere at once. It's about respecting my time and ensuring that my commitments align with my priorities and contribute meaningfully to my goals.

Take some mental space and meditate; use vacations and office work from home policies seriously.

Boundaries! (Communicate and then stick to them!)

Prioritize your tasks and set realistic goals, ensuring a healthy work-life balance. Don't forget to engage in regular self-care, including exercise and adequate rest. Embrace continuous learning and be willing to adapt, and manage stress (using whatever techniques work best for you personally) to stay productive and mentally healthy.
