MY FAVOURITE TV PROGRAM

Today I am going to talk about my favourite TV program. It has been too difficult to choose only one, but I think the show I always enjoy is the Carpool Karaoke with James Corden.
The program is very simple. James invites to celebrities to his car and then, they talk and they sing a small variety of song<font style="background-color: yellow;">s</font>. Obviously the most <strike><font style="background-color: yellow;">of</font></strike> invited people are singers. Also, Its duration is at most 30 minutes.
I <font style="background-color: yellow;">really </font>enjoy<strike><font style="background-color: yellow;"> so much</font></strike> this show because it is very entertaining. You can see a lot of artist<font style="background-color: yellow;">s</font> talking happily about <strike><font style="background-color: yellow;">the</font></strike> life and singing songs with an excited TV presenter. They always have fun! One thing I miss is that James <strike><font style="background-color: yellow;">hasn’t still</font></strike> <font style="background-color: yellow;">still hasn't </font>invited<strike><font style="background-color: yellow;"> to</font></strike> Rihanna. I <font style="background-color: yellow;">have</font><font style="background-color: rgb(255, 255, 0);"></font> look<font style="background-color: yellow;">ed</font> up to Riri since I was a child and I look forward to seeing her in my favourite show.

Now is your turn. What is your favourite TV program?

Your English is wonderful!!!  My favourite TV program is Steven Universe.  

*Note.  Native English speakers usually say TV SHOW instead of TV PROGRAM.  Both are correct, though.  Good job! :D

please help me correct my mistakes !

How to control anger ?

Anger is a reaction we get when something we dont expect happen<strike>ed</strike><font style="background-color: yellow;">s</font><font style="background-color: yellow;"></font> . You must know that anger is a frustrating behavior for other people who live with us . Anger has bad effects on <strike>either</strike> <font style="background-color: yellow;">both </font>yourself and others.
But there are different ways to control it.

For example, if you are getting angry, you can drink water . <strike>w</strike>Water is very helpful for it and while you drink , you have a short time to think about your behavior. Also you can listen to music . It helps you to forg<strike>o</strike>et what happened and prevents you from behav<strike>e</strike><font style="background-color: yellow;">ing</font> badly .

Rese<strike>s</strike>arches show that people who can control their anger have longer live<font style="background-color: yellow;">s</font> and they can solve problems easier, and that <strike>said </strike>peace and behav<strike>e</strike><font style="background-color: yellow;">ing</font> peacefully can help you to focus your mind . It is clear in this case that you can decide better and easier .
You must know, even if you are very angry , you can control it . You just need to find a way which is more effective <strike>on</strike><font style="background-color: yellow;"> to</font> you .
