Hello to everyone who speaks fluent English. Could you please help me? I am writing a thank you card to my manager. This is what I plan to write. If you have any ideas, could you please share them with me? I would like to thank you for everything, Mr. ____. Thank you for all the years of guidance and advice you have given me. Working under a boss like you really elevates my whole work experience. Your motivation and kindness are just a few of the qualities that make you a great leader. "Bestowed upon me" is a too formal in my opinion. "Have given me" is more natural but still proper and respectful. Otherwise, your words are very nice and I like the phrase "elevates my whole work experience". Nicely done.

Because it’s to my work manger but what can I say instead!
