You start your day running to your first appointment. When you get there you find that you don't have what you need. It's time for you to slow down, and plan what you're going to do before you take action. It seems counter intuitive, but you'll get more done faster with less stress if you set aside proper planning time. You love action and you would rather be doing than thinking. You're confusing activity with progress.
All that unfocused activity is making you tired and stressed because it isn't helping you to do the things that produce the best results. Start the day by planning your day the day before so get organized. Take 15 minutes before you end your day to plan the first thing you'll do the next day, and what you'll need to do it so you can start your day right and get better results.
Plan how you'll start your day start with the most important thing you could do that day. Schedule your most important appointments, phone calls, and actions for first thing in the morning. Each action you'll be take must have a clear objective. Know exactly the outcome you expect from every appointment. The same holds true for phone calls. As you start your day Know exactly who you will call, have an agenda for the call, and identify what you want to accomplish as a result of that call.
Without clear objectives you waste valuable time and you get poor results. You're running around working harder than you need to and you aren't getting the results you want. If you don't know exactly what you want from your actions you can't expect someone else to know.
You thrive on solving problems and making things happen. When a customer or prospect calls you drop everything and immediately respond, but that isn't a demonstration of good time management skills. It just means that you'd rather be reactive than proactive.
You'll better serve your customers, prospects, and yourself if you develop a planning habit. Your current habit of reacting rather than planning is causing you to receive poorer results than you could be. If you'll plan before you act with a clear understanding of your objectives and be organized in your approach you can enjoy great success and free time.
