Serenity Prayer

I don’t know about you but for me, I usually find myself wasting my time and energy to change things that I cannot change.

What I need is to accept it, not change it but the thing I can change, I need courage so I can change it.
But the problem is I sometimes, maybe more often than I want to admit, I can’t tell the difference between these two things. So, I desperately need wisdom to differentiate between the two.
But few things are so obvious. I mean, can we change others? We can’t. And wisdom says to us: “You cannot change anyone but yourself!”
If so, why do we try to change others? ///
