Hello Zaineb. You should always write the title with initial capitals. You are writing in the past tense as you start with 'bored' so need to say 'started' and 'been' in the same sentence. In English, we do not start a sentence with 'but' or 'and' usually. Otherwise it is fine. I have just suggested a few amendments. "Stuff' is not a very descriptive word to use in writing as it means just about anything - you could just say 'amount' or 'amount of information'.
