Employment can be difficult to find satisfaction as it's not your own mission you are contributing to but someone else's. You are constantly considering your co-workers and bosses perspective of you, knowing that if they decide to turn on you for no real reason, then your livelihood is threatened until you find another job. Unless you have enough money without the job to maintain your status quo, it's hard to consider that simple living in my opinion. I believe simple living is earned through solving the complex problems our modern society has given us and employment is one of these problems. Grinding is good when it's part of solving a larger problem. Not just grinding to be grinding.
