I want to give some advice casually. Consider this sentence,
Just a reminder: If you think you can make someone's day please do it, cause the world need more love.
Here, I love the way the phrase "Just a reminder" has been put in at the beginning.
Similarly, I am looking for an introductory phrase to casually give advice. For example,
Settling the issues with anger is easy, you must have the courage to actually explain to your child the actual thing.
I thought some phrases might be,
Just an advice
Just some casual thoughts
But you see, they are not really appropriate for my case. Can someone suggest better phrases?
