Writing

manuscript

I have a manuscript about traveling.

A 'manuscript' is a written document that hasn't yet been printed as a book or article.  Notice the following:

1. He sent his manuscript to over a hundred publishers before it was accepted.
   
2. They sold the original manuscript at an auction last year.
   

come in contact with

I write about people I've come in contact with.

The people you 'come in contact with' are random people that you meet, talk to or have an interaction with.  Notice the following:

1. He comes in contact with sick people every day.
   
2. Do you ever come in contact with celebrities?
   

put the time into

I thought anyone could write, if you just put the time into it.

If you 'put time into' something you work on it and put your energy and effort into it.  Notice the following:

1. If you don't put time into learning you will never improve.
   
2. She puts a lot of time into her school projects.
   

physical book

Think about this whenever you pick up a finished product, a physical book.

A 'physical book' is a printed copy of a manuscript that has been published.  Notice the following:

1. I could spend hours around physical books.
   
2. I have an electronic reader, but I still prefer physical books.
   

underestimate

Do not underestimate the time and effort that has gone into it.

To 'underestimate' something is to undervalue or misjudge it.  If you underestimate the time it takes to do something you think it can be finished faster than it really can.  Notice the following:

1. She always underestimates how long a trip will take.
   
2. Be careful not to underestimate her abilities.
