Things all grad students should do early on

1. Create a file system for printed papers that you have read in alpahbetical (or any other indexable) order. When you read a paper, write comments on it with a pen. Mark main contributions, shortcomings, a bad assumption, an ingenious proof, and anything else that catches your eye. When done reading, put it in its place.

Take it from a veteran that in time you will remember almost no details of a paper that you had once read in depth. Keeping a commented version makes re-reading much faster. Not to mention that disorganized papers are nowhere to be found where needed, and are responsible for much paper wate.

2. If your work involves simulations, use version control of some kind. Softwares are available for every platform.

3. Again, if your work involves extensive simulations, learn about reusing code. Tons of well-written code is available online.

That way, you will get much more work done. Or, if you prefer, you will get more time to spend on "non-academic" activities such as blogging :)
