You perhaps took my suggestion of capitalisation a little too literally! You need a capital letter at the beginning of each sentence, and always capitalise the word "I" (and proper nouns of course).
Please note that there should be an apostrophe in "it's" in your post, as it is an abbreviation of "it is".
And don't forget to your sentence with a full-stop.
