Attitude is more important than skills.
Most people and almost all things taught at school are on skills. Yet more than ever attitude is more important than skills. Ever hear of on the job training? Of course, we all have and get on the job training.
Can you train someone that doesn't show up? Can you train someone that is physically present and mentally absent? Of course not.
You know that person that is unhappy, points out the "problems" and "helps" other people see all the "problems"... In other words, turns present excited people into unhappy unexcited people.
Then you know that positive person that adds energy to everyone around them. Turning mentally absent people into excited mentally people?
Attitude is key. Attitude is where it all begins.
