First, consider purchasing a notepad and carrying it with you for a week. Take notes on your thoughts, conversations, and activities this week. This will allow you to see how well you are allocating your time productively or, conversely, how much of your day you waste. The next skill you’ll need to master is knowing the difference between what’s necessary and what can wait. Before going to bed, successful people only make a to-do list of three or four of their most important tasks. They begin the day with the most important and possibly most difficult task. When they finish a task, they cross it off their list.
