Since we have so many things to do every day, we need to make plans beforehand to make sure our studies and life will be organized well and not end up in a shambles. Nonetheless, making plans is not always an easy job and may turn out in ways not originally intended.
Take my last winter holiday for example. I had a lot of work to do at home, so I thought it would be a good chance to do it. But then I decided I'd rather not spend the holiday that way. I could work at home all the rest of the year. I had long ago heard of the beauty of the Rocky Mountains, and I decided this was a good chance to go there. But it was too cold that time of the year, which reminded me of the warm weather in the south.
Why not go to the seashore? I talked myself into going.
I could go to see the Rocky Mountains next time after all. When I started packing for my trip, it occurred to me that it might rain at the seashore and I wouldn't enjoy it at all. I guess you can imagine what happened at last. I ended up going nowhere. My personal experiences show that indecisiveness is fatal when making plans.
