Lifestyles: how's your experience?

I find them to be a mixed bag, right now one of my sims who is supposed to be active is close to getting the low-energy lifestyle because I wanted him to focus on his job and level up his logic skill. I'm not a huge fan that I have to pick another job or get him to not focus on his job just because he is supposed to follow a specific lifestyle.

Luckily, they warn you with messages early so you can prevent them from getting a lifestyle that you don't want. You can apparently remove them by using the computer as well, but I have heard that removing them could be bugged.
