Of course there's not enough time to train anybody if you continue to insist that you must do everything yourself. Sometimes it's much better to take a step back and invest some time in getting the right people to do certain jobs rather than doing them yourself and perpetuating the problem. However, when you're locked on the treadmill of insufficient time it's hard to be realistic and objective. My sincere hope, if you've read this far, is that you will read on and take a cold and objective view of what you can really do with your time. Set your goals and write them down.
Many people are poor time managers because they have no real idea of what they want to achieve.
If you don't know what you want to achieve it's easy to tackle any task that comes along regardless of its importance to your ultimate objectives. So, find some time soon to just sit down and focus on your objectives in business and in your personal life. Determine what's important to you and where you are now in respect of those important things. Then decide where you want to be and what you have to do to get there. These then become your goals, and once you know them, the rest is easy.
