When expressing an opinion, sometimes it's helpful to start with a phrase that indicates that what you're about to say is only your personal perspective. "To my mind" is a common phrase that is often used in this context. However, if you want to mix things up a bit, there are a variety of synonyms that you could use instead. Some possible choices might include "in my view," "in my opinion," "as far as I'm concerned," "from my perspective," or "to my way of thinking." Using different phrases to express the same idea can help keep your writing or speech interesting and avoid repetitive language.
