I am sure this list will expand in the coming months and years, but these are three things that I have realized recently. Beats me why it took me so long to realize them.
1. No matter how thorough you think your conceptual framework is, there will always be something out there that could debunk your whole research.
2. When you organize your articles (soft copies) on your computer, forget APA referencing style, start off with the title and leave the authors to the very end.
3. Don't wait till you have accumulated piles of files in your download or documents folder before organizing. Organizing can be a pain in the behind when you wait too long.
