I'm just a single point on a complex plane. I'm not the strongest species that survives, nor the most intelligent, but the one most responsive to change. You can't teach me anything, but you can stimulate me to think! I am a detail-oriented analyst and interested in almost everything. Consistency, optimization, best-practice, & perfection are always my first priority in mind! Therefore by my questions & answers you'll fully recognize me. I can tell you more but then I have to kill you.

I distribute my rep in bounties as spending money for my & your pleasure is more meaningful than saving money in a bank & abandoning it unused.

"If you're an underdog, mentally disabled, physically disabled, if you don't fit in, if you're not as pretty as the others, you can still be a hero, read TEXBook!"

"Motivation isn't enough. If you've an idiot & you motivate him, now you've a motivated idiot."

Learning (La)TeX, PSTricks, & PGF/TikZ is similar to learning how to swim or drive a car. You don’t get the full benefit by watching someone else do it. Your own fingers must get involved.

Don't be lukewarm! If you cannot be the best, be the worst!

Beauty without intelligence is a masterpiece painted on a toilet paper.

For every problem, there is always a solution that is simple, neat, but wrong.

Best practices

  1. Use pdflatex \input{filename} instead of pdflatex filename.
  2. Don't specify the file extension in \includegraphics.
  3. Divide your project into a main & smaller input files & compile the main with pdflatex.
  4. Put each code snippet 4 either drawing a diagram or making a table into a standalone input file & compile it to produce a PDF.
  5. Define global macros 4 often-used materials, put them into a separate package thereby changing the macros in one place will effect the whole document.
  6. Remove unnecessary packages.
  7. Don't mix different series, families, font size, & shapes, ESPECIALLY IN ONE SENTENCE.
  8. Obey.

@CasperLi: It depends on the text editor you are using. If there is a shortcut key for each macro then you can type much faster. But I think the important point is your typing speed. :-)
