My standard LaTeX prelude defining common packages used, helpful commands, etc. Use at your own risk; although most of this is pretty generally good, it does contain some me-specific features (such as commands for my advisor and I to make comments tagged with our initials, etc.)

If you decide to use it, either place prelude.sty in your LaTeX project root directory or in your user's texmf directory (usually ~/texmf/tex/latex/prelude for this package in particular).
