As in, do you have a .tex file from which you begin every document? This hypothetical file would contain most of the things you use in each document on a regular basis. For example, here's my "template".
\documentclass[10pt,letterpaper]{article} % Basics
\usepackage[utf8]{inputenc} % Inputs
\usepackage[T1]{fontenc} % Inputs
\usepackage[margin=1in]{geometry} % 1 inch margins
\usepackage[pdfauthor={author}, % Begin PDF metadata
pdftitle={title},
pdfproducer={LaTeX with hyperref},
pdfcreator={pdflatex}]{hyperref} % End PDF metadata
\hypersetup{
colorlinks, % Begin setup of link colors
citecolor=black,
filecolor=black,
linkcolor=black,
urlcolor=black, % End setup
pdfpagemode=UseNone % Disables bookmarks sidebar auto appearing
}
\title{title}
\author{author}
\date{\today}
\begin{document}
\maketitle
Insert body here.
\end{document}
I get the feeling that I'm missing some essential packages, but that's what I use to start out each document I make.
.styfile that contains all the packages and settings you desire. Then, if you come across a slight tweak that a document needs, you can include some conditional compilation in the.styfile. But you should start off with the bare minimum you need and only add packages as you need them. If you are going to be doing any math in your documents you should also includemathtoolspackage (it already includesamsmath). But these should be enough packages to get started. – Peter Grill Jun 27 '13 at 00:20
