Kacey Musgraves feels as if she has to be "ruthless" in life.

The 35-year-old singer has come to know herself better than ever in recent years and is not worried about cutting certain people out of her life if she needs to as long as she is "in tune" with what is best for her.

She told People magazine: "I know myself better than in previous years, previous albums, and I just feel like I'm right where I need to be. I definitely think the music reflects that.

"This life is so short. I think that you have to be a little bit ruthless in removing obstacles for growth.

"That could mean adjusting your expectations with family members. That could be putting a pause on a friendship. It could be a breakup or dropping a habit that just doesn't serve you well anymore. It's being awake enough to be tuned in to paying attention to what the flow of nature is trying to tell you about what you need."

The 'Follow Your Arrow' hitmaker ahead of the release of her new album 'Deeper Well' explained what while she doesn't have any children of her own, she likes to think of her projects as her own offspring.

She said: "I don't have children, but I can imagine it's like sending your kindergartner off to school for the first time. It's scary, but it's exciting ... you're proud.

"There's also a letting go process to it, where you make the music and then you put it out and it's not quite yours anymore — it's everyone else's. But then, the next wave of inspiration will come along and there's beauty in that too.."
