Taking the initiative is hard. It is uncomfortable. It makes me wince.
I always think of the worst scenarios when I think of raising my hand. Is someone going to call on me and allow me to embarrass myself? Is the rest of the class going to laugh? Will they banish me in the prison in the basement (I get this ridiculous). None of these things have ever happened to me when I raised my hand. In fact, the opposite generally happens. I usually answer something or pose a better question. If I don’t, then usually someone says something that gets me back into the right frame of mind. It’s generally a win-win, and I don’t need to worry about being jailed in some imaginary dungeon.
Many great journeys in life begin with a touch of uncomfortable.
