What is a noun or adjective to describe somebody who juggles work, study, hobbies, family and more?

I'm trying to describe someone who burns the candle at both ends. They work full-time, they study full-time, they have creative projects on the go, they raise their family and manage their property - etc... all at the same time.

I want to use a word to sum this up but will also hang a small definition on (similar to what is above) after the word to clear up what it means.

Words like multi-tasker spring to mind but this does not convey the meaning I want to give. I also considered words like dexterous and agile - but again, these don't seem quite right.

Given that people often use the term 'juggling' to describe people that 'juggle' their work, study and private lives, I thought there might be a nice adjective to describe the skill that a good juggler has but I can't find something suitable for this either.

Any help or ideas greatly appreciated. The context is that of a reference for employment or a CV.

Industrious. Ambitious. Assiduous. Productive. Hardworking. Hyperactive.

There is no word that specifically captures the exact notion you are describing, that is why we use sentences composed of multiple words to express nuanced ideas. The words provided above could fit your needs depending on context.

I can't think of a word to describe this but saying "(The person's name) juggles (his/her) work, study, family, and hobbies with grace/poise/great success" is more than adequate.

There is a concept called work-life balance which is the result of balancing all the different aspects of life. And the person who achieves this is called a work-life balancer colloquially.

Work–life balance is a concept including proper prioritizing between "work" (career and ambition) and "lifestyle" (health, pleasure, leisure, family and spiritual development/meditation).

But a more common adjective would be well-balanced or well-rounded. Of course, these adjectives has a broader meaning without a context so you can say:

a person with a well-balanced lifestyle
