This article has given two important reasons why we should have a blog to record something we've learned:
- For our own reference. We are human beings, and human beings are prone to forgetting things. This is why I write down things here.
- For someone else who needs the solutions you've just found or figured out. When someone else are trying to Google the solutions and you happen to have them in your blog, then people might have more chances to find these solutions. That's good!
