Lol. I'm not worried about a thing, my friend. Very confident in what I bring to the table and comfortable with my distractions (age, old/bad GPA, etc).
To me, your guidance is a little misguided and I'd hate for others to think it was sufficient. Most of the people whose apps I review or stats I see, have more than 100+ hours in shadowing. That's all. 🙂 Cheers!
