Howard Wolowitz (Simon Helberg): Give me a compliment.
Sheldon Cooper (Jim Parsons): Fine. You have very tiny hands.
Howard Wolowitz: No. About my job. I want you to tell me I'm good at what I do.
Sheldon Cooper: You're obviously good at what you do.
Howard Wolowitz: Well, then why are you always ripping on me?
Sheldon Cooper: Ah, I understand the confusion. I have never said that you are not good at what you do. It's just that what you do is not worth doing.
— The Big Bang Theory, S5-E21, 'The Hawking Excitation'
In the funny and whimsical universe of The Big Bang Theory, Sheldon Cooper (Jim Parsons) often pulls down his friend Howard Wolowitz (Simon Helberg) for being an engineer and not a physicist with a doctorate like him or their two pals Leonard Hofstadter (Johnny Galecki) and Rajesh Koothrappali (Kunal Nayyar). Never mind that Howard graduated from MIT, went to the International Space Station and came back an astronaut.
Sheldon, we are told, is somewhat peculiar and known for his blunt honesty, but he doesn't mean to be hurtful or malicious.

You make such a good point here! We need to have faith in ourselves. To me, that means accepting that we'll fail sometimes, but that we are capable and have talents.
