I am not an event planner, but I feel this is a question that is important for any profession.
Always make sure to include some 'me time' into your schedule. 'Me time' can be anything that you find relaxing. For example, I carve 30 minutes out of my day to sit down with the book I am currently reading. I put away my phone and all things work. I empty my mind and go to another world through my book.
Your 'me time' does not have to be reading. It does not have to be everyday, nor does it need to be 30 minutes. It really is about the 'me' in 'me time'.
Here is a TED talk that came to mind from reading your question: https://www.ted.com/talks/shonda_rhimes_my_year_of_saying_yes_to_everything
This professional recommends the following next steps:
- Think about activities that you enjoy and leave you relaxed
- Make time in your schedule for these activities and stick to it
- Your version of me time may change over time and that is okay
