Today you're allowed to be vague.
For example what types of job titles if you're an actor: talent agent, casting director, actor management. For example what types of companies if you're an actor: theatre companies, straight play company, musical theatre companies.
Do not list the exact name of every single person that is a talent agent, every single theatre company in your area, etc.
That's too specific and we will get to that in week 3.
All you have to do today is concentrate on the fluff of types of job titles, types of companies, types of directories.
Don't get too specific.
And if you don't find anything then don't worry about it. Move on and make it work for you.
