I Like Doing Sports, What About You?

Suggestion.

I like both yoga and going to the gym to exercise. I think that exercising is good for a person's health. Also, in the holidays, I like travelling. I would like to meet new friends from all over the world. Lastly, my hobbies are skiing, reading and playing musical instruments.

-All words in titles should start with a capital letter (apart from small words like "and", "of", "at" and "in" etc.)

-You need to put spaces after there punctuation marks ".", ",", "?", "!", ";", ":" and not before them

-Brackets "()" work like this - (I am in brackets). You put a space on either side of the outside of the brackets.

-"I" is a proper noun which means that it always needs to be capitalised. 

-All sentences must start with a capital letter.

-When you write a list, put a comma between all items apart from the last two.

I hope my correction is useful and if you don't understand anything let me know. :)

Laurence brings up an interesting debate in English regarding the use of commas in a list. The comma before an "and" in a list is called an "oxford" or "serial" comma and leaving it out potentially changes the meaning of the sentence. In your example, omitting the serial comma could mean that you have *two* hobbies: 1) skiing and 2) reading (while) playing musical instruments. I like using the serial comma which clearly makes it 3 items.

I like doing sports , what about you ?

I like yoga (,) and,  sometimes , I will go to the gym to take exercise. I think that is good for my health. When I have a (.. And in my) holiday , I like traveling/travelling. (,) I  would like to meet new friends from all over the world. ( ,and) My hobbies are skiing , reading and playing musical instruments.  What about you ?

Just to be careful with 'I' which, on its own, is always written with a capital letter in English.
