Question: What is the difference between "investment" and "sacrifice"? In your February 26, 2012 webcast, you indicated that you regard sacrifices as something very different from investments. But doesn't sacrifice just mean giving up something? In that case, don't investments in the future require sacrifice now? Or: What's the difference between sacrificing some ease and comfort for your goal versus investing time and work to achieve a goal?

Question: Is it moral to help inept co-workers? On my team at work, we have only a very few people who use their time productively. We all get paid for 8 hours of "work", every day, but most of my team would rather talk on their phone, hide from management, and underperform at their job. We also belong to a union, which makes it harder for management to fire the ones who don't work despite being informed about the situation. I often find myself in the position of helping these people, or going in behind them and fixing their work. I am beginning to feel taken advantage of, and am getting fed up with most of my co-workers. Is it moral to continue helping people who do not take their own work seriously?
