As someone's manager I want them to know that these things are NOT roads to "success." Not everyone though has the makeup or fortitude to tell their boss no, and bosses who take advantage of that are a real problem. What is worse is someone who was so talented and now they are worthless because they can't find any motivation to do anything. Its like being so sore from exercising that you can't walk, and if you can't walk you can't work the lactic acid out of your muscles and you're going to be incapacitated for a lot longer.
