Planning through the years

Have you ever had difficulties with visualizing long periods of time?
For example, you have a business idea. According to circumstances, you can’t realize it in a short term period. However, you want to remember this idea or maybe you need to make some serious steps to it and so on. Once you realize that your long-term plans are very blurred. Notes cannot really help you, because if dates are stand far one from another – date symbols and numbers will tell you nothing. And that is the problem.
However, digress of this problem and think about such question. What is the time for you? What picture do you see, when you try to imagine a year?
For example, for me one year is an oval. Bottom is a summer, top is a winter, left side is a spring and right side is am autumn.
Moreover, I circle as times go by counter-clockwise.
Remember, it is my personal fancy! Maybe your image will be different. The main thing is to find your personal fancy.
Once you have found it, create a mind map with your plans for one, two or more years. Just place months and seasons as branches in your personal manner accordnig to your fancy. Next-level branches should be your steps to this time. In the end, you will have a plan, which let you easily visualize your life for a ling-term period.
