It is easy to find problems. Many people know they are overweight. Or that something at the company is not working well. And is easy to point it out.
But no one will pay you for finding trivial problems and pointing them out. And it will also not help you personally.
What is much harder is to find solutions to the problem.
And what is really difficult is applying the solutions and get things done.
Unless you can do that, your life and career will never move forward.
