“By working faithfully eight hours a day, you may eventually get to be a boss and work twelve hours a day.”

Simplified Meaning:

If you consistently put in a lot of effort and work hard at your job every day for eight hours, you might get promoted to a higher position, like a manager or a boss. However, that promotion often comes with more responsibilities. This means that instead of working eight hours a day, you might have to work even longer, like twelve hours a day, to handle all the new tasks and duties that come with being in charge. For example, think about a chef in a busy restaurant. When they start, they might work regular shifts cooking meals. If they work hard and do a great job, they might get promoted to head chef. As head chef, they have to plan menus, order supplies, and oversee the kitchen staff, which means they will be working much longer hours than before. The advice here is to be aware that higher positions usually come with more work. One can apply this by considering both the benefits and challenges of moving up in their career. It's a reminder to weigh the extra efforts required before aiming for a promotion.
