I'm not being nasty but you gotta grow a spine and go all in or get out. If you want big rewards, you gotta take big risks. You looking like a fool? Man, Trump stands to lose more than you in terms of humiliation if he loses and listen to him last night! He was over the top saying that not only is he gonna win, but he's gonna flip the house to red as well. Trump takes big risks and doesn't fear looking foolish - that's why he's so successful.
And if he, by some tiny chance in hell loses? Laugh it off and laugh at anyone who calls you a fool. My mother used to tell me all the time - "No one can make you feel bad without your permission". Stop giving people power over you.
