It's important to use your available holidays across the year. There would be times where I work the whole year and only take time off in December, by then I've already burned out. As with anything, it's best to go at a steady pace.
Personally, I wouldn't call myself a lazy person, I do enjoy my career but I'd like more out of life and refuse to become a slave to the 9-6 for the next 20+ years.
I've love more time during the week to do things that I enjoy that don't necessarily pay the bills such as learning to play an instrument, coding a videogame, practicing art, etc.
However, to do that, I needed to become financially independent; i.e, being able to pay for my lifestyle without having to work. I started my investment portfolio not long after I graduated and with some luck, I've been quite successful. Despite living financially without worry, I do get bored after a while whenever I'm not working. Days feel longer and more lonely.
Why lonely? Because my friends are all out working and studying like the rest of society. Consequently, I continue to work like everyone else. Admittedly, 9-6/5 days a week is still a bit much for me, I'm working hard in my career to become expert enough to act as a consultant engineer picking up contract jobs where I can finally work according to my desired work / life balance.
