I'm sure every software developer would realize it over period of time. It is easier to write a code from scratch for any given design requirement. I feel more productive while I add a new feature or add an enhancement to an existing functionality. Probably thats why in the "Software Engineering" book, Pressman suggest to do 'rm -rf *' and write everything from scratch. Because, by that time we know what to do and what not to do in the project.

Code review is another interesting area for me. I like to review and comment on others code. Similarly, I feel happy if someone provide review comment for my code. On the other hand, I find it bit difficult, or rather time consuming to debug and fix a bug. However, it is the only way to understand the code better.
