Have I used the word "where" in the right place in the following sentence?
Life is where my heart is.
Have I used the word "where" in the right place in the following sentence?
Life is where my heart is.
If you literally mean that the location of the mentioned life is in your heart, which means you can find life within your heart.. Then I don't think this is a wrong sentence, it's grammatically perfect.
Different opinion would count if you meant another thing other than that.
Your sentence sounds strange to me. I think there are two reasons:
1) As @snailboat pointed out, there is a saying in English:
Home is where the heart is.
I think your sentence is too close to this saying, and it sounds like you misremembered the saying.
2) I'm not 100% sure what idea you're trying to convey. You could be trying to say any of the following:
My life is important to me.
What's important in my life are the things I love
I have dedicated myself to having a fulfilling/interesting/important life.
