英文小作文：

I always have ideas for new projects or ways to improve things, but sometimes it"s hard to know which ones are worth pursuing and which ones are just passing thoughts. To help me make better decisions, I like to write down my ideas and evaluate them carefully. For example, if I have an idea for a new product, I"ll research similar products on the market and see if there"s a market demand for it. If there is, then I know it"s worth pursuing further. If not, then I can move on to other ideas that might be more suitable for the market. By doing this, I can avoid wasting time and resources on ideas that won"t work, and focus on the ones that could be successful.
