Firstly, check the spelling of "correct" and "grammar" in your title.
Secondly, look at your sentences. We do not capitalise common nouns, pronouns or verbs in English (love, happiness, etc). We sometimes capitalise every word of a title or a caption, but we don't randomly capitalise some and not others.
Thirdly, start every sentence with a capital letter.
Have another look at what you have written and see what amendments you can make based on my three points above.
