There is a difference between effort and success.
Effort refers to the amount of time and energy invested into a goal.
Success refers to the actual achievement of a goal.
Just because a person makes an effort doesn’t mean their efforts will pay off in the form of success.
Plainly put, sometimes we try and fail.
The best kind of constructive criticism is the kind that can be honest about the lack of success while simultaneously being respectful of the effort that was made.
When people fail, they need straightforward feedback.
Just remember that the only reason they failed in the first place is because they cared enough to try.
It’s okay to acknowledge that part too.
