There are easy ways to do things and there are hard ways to do things.
In modern society, most everything is done the hard way. No wonder, therefore, that people become old and decrepit before their time. That's one of the consequences of always finding the hardest, most cumbersome, difficult, backbreaking, arduous, and laborious way of doing things.
Take weather forecasting, for example. Like everything else in life, there is an easy way to forecast the weather and a hard way.
The Easy Way
The easy way is by intuitive observation. (Oh p-lease, spare me the howls of incredulous laughter --- it only betrays a closed mind.)
Here's how it works for me. If I want a short term forecast, I go out the back door and look at the birds. For a long term forecast, well, I have to wait until it arrives. (I've already received my long term forecast for next winter.)
Short term forecasting is accomplished, as I said, by observing the birds. Here's a sample:
Flocks of crows mean a heavy cloud cover probably with heavy rain and wind. Water birds, e.g. ducks, oyster catchers, gulls, etc. indicate rain. Pigeons indicate clear spells. Flocks of crows interspersed with pigeons flying past, means heavy clouds, etc, with clear spells in between. If I hear geese at night, then I can expect low clouds or fog.
Last winter, I received a four week forecast from an owl (well, not in person, of course). When I see or hear an owl, this interprets as a short cold snap of one day or so, followed by a longer period of milder weather. One night when driving home at dusk, I stopped the car to watch a barn owl hunting along the hedgerow. Instead of flying off, the bird flew just ahead of the car, alighting on fence posts every so often. I followed the owl for nearly 10 minutes. I interpreted this as a weather pattern of short cold snaps followed by milder weather --- and that is exactly what happened.
Last winter's long term forecast was received in September. Reading a number of novels in quick succession, the phrase "late snows" (occurring in each of the novels) jumped out at me. In my part of the world, we did indeed have late snows and a cold spring. My long range weather forecast for the winter before last was also correct.
How do I know which birds to pick out from the mass or which words or phrases in books to pick out from the mass?
Through intuition. This will not work for you unless, among many other things, your intuition is well developed.
With practice you can learn to do this too.
