How Can I Effectively Structure a 3-Hour Presentation on Attitude for a Mentor Role?

Hi Folks, I applied for a soft skills mentor position at a company here in Chennai. They have asked me to lead and deliver a powerful presentation on ATTITUDE. I find this topic very interesting, but I haven't been able to gather much information. Could someone please help me with how to structure a 3-hour presentation effectively? I would appreciate your inputs on the content and the procedure.

Cheers,
Yogi

In Professional Life

Bad Attitude
• I have the most boring job on Earth.
• My boss is too demanding.
• This company needs to pay me more and treat me better.
• I should get more vacation time.
• I always have to do the "grunt work."
• No one here appreciates me.
• I may have to work with these people around me, but I don't have to be nice to them.

Good Attitude
• I am so thankful to have a job.
• I am going to do my very best every day.
• I believe that God gives me favor every day with my boss.
• I am glad to be part of a team with my coworkers even though none of us are perfect.
• The work environment may not be ideal, but I will do my part to make it pleasant for myself and those around me.
• I am committed to being focused and diligent while I'm on company time.
• I would like a raise, so I will work hard to earn it :)
