Hey, I have been lifting weights and I'm now bigger than your average Joe in the street. (The average Joe in my street ain't fat btw, I don't live in America.) I am not afraid of physical fights, at all. I don't pursue them, but I'm not backing down.

However, the place I lack the most confidence is in verbal conflict. I seem to lose every argument and debate, because I suck at it. This has caused me to avoid debates and arguments

How do I practice this without arguing with every friend I have and burn down bridges?
