Things happening that are beyond your control are to your benefit.
For example: You are dreading an upcoming exam because you don't feel prepared. The day of the test your teacher announces that because of computer problems the test will be postponed a day, giving you one more day to study.
"Favourable turn of Events"
Means that a situation or some situations have changed that favour your interests.
Things are going your way, something unexpected.
I do aim to please.
