Hand in vs. Hand out

If you hand something in, you are giving something to a person of authority. If you hand something out, you are giving something to a group of people. 
Hand in = a group of people giving/ submitting something to one person  
Hand out = One person giving something to a group of people.

1. It’s a “madhouse” trying to hand out sweets/ candy to a bunch of kids at any party. They will crowd around and attack you… so it’s best to throw the sweets into the air and watch!

2. When you were at school, were you one of the responsible kids who used to help the teacher hand out the worksheets? In any class, one person can hand out the worksheets or the group itself can just pass them around, which means that each person takes one and passes the rest on. If you ask someone to hand something out for you, you can also say, “Could you please pass these out for me?”

3.  Have you ever handed out pamphlets or flyers in a public place to promote anything?

Get out what you put in

This expression means that you will only benefit from something to the degree of effort that you make or put in.

1. The cold, hard fact is that when it comes to learning English (or any language for that matter) you only get out what you put in… so if you study for 5 minutes once a week, you won’t see much of an improvement in your language skills or communication.

2.  Some similar expressions to “You get out what you put in” are: “You reap what you sow”, “You are what you eat”, “No pain no gain” and “You get what you give”.

3. What you get out of any relationship is what you put into it. If you spend quality time with your family or friends, you will create memories that will last and build unbreakable relationships. This is especially true in any marriage.

4. Have you heard of the expression, “Life is what you make of it.”? It means that what you put into life is what you will get out of it. Do you feel that you have had many opportunities in life and the freedom to make your own choices? People who are constantly complaining and who are generally pessimistic don’t understand that their lives could be so much more different and happier if they made an effort to be friendlier and more accepting of other people… as well as starting to put more effort into certain areas of their lives so that they could benefit (in time).

Turn out

If something turns out well/ good, it was a success, there were good results. If something turns out bad(ly) then it was a failure or there were bad results. Turn out = the end results.
-> How come? = Why?

1.  Life seldom turns out the way you expect it to. Life has so many twists and turns, and normally you could never imagine where you will be or what you will be doing 10 years from now.

2. If you follow the instructions on a recipe “to the T” (very carefully and precisely), whatever you are cooking should turn out well.

3. Thank God that you don’t need to be a perfect parent for your children to turn out OK. Do you think you turned out OK (had a good upbringing/ education)?

4.  When a new job is much better than the old one, you can say that it turned out well for you (Changing jobs).
