I was going to suggest you put this in the NOTES section instead of ANSWERS, but there wasn't much to correct. I had really work to find something! Mostly commas, but I got to correct your last sentence! ;-)
"...reading, books and..." Insert comma after "reading."
"...taking photographs, and surfing..." Insert comma after photographs.
"...view, nowadays..." Comma :-)
"... In the future, I would..." Comma
"In conclusion, I want..." Comma
"... I want to say that hobby is an essential part of our life.." Since you use "our," the sentence would read, "...I want to say that hobbies are an essential part of our lives."
