[![enter image description here][1]][1]as I applied the enumerate to generate the numbered list for my latex file, unfortunately the second page pdf output generate bit different than the first page. here is the MWE:
\documentclass{book}
\usepackage{enumitem}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\setbox1=\hbox{1.}
\setlist{noitemsep, topsep=0pt, parsep=0pt, leftmargin=1.8cm, labelindent=1.2cm, labelwidth=\wd1, itemindent=*, labelsep=\dimexpr0.6cm-\wd1}
\setlength{\parindent}{4em}
\setlength{\parskip}{1em}
\begin{document}
\pagestyle{plain}
\begin{enumerate}
\item \textbf {What is Lorem Ipsum?
}\\
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
\item \textbf {Why are you motivated?} \\

\item \textbf{Why do we use it?} \\
1. Where does it come from?
2. Where can I get some?
3. Why do we use it?
4. Section 1.10.33 of "de Finibus Bonorum et Malorum", written by Cicero in 45 BC is okay?
5. Section 1.10.33 of "de Finibus Bonorum et Malorum", written by Cicero in 45 BC is valid?
