Confidence is a few things, let us cover some. Someone who is confident could be seen as someone who will take charge when needed, someone who can approach any situation without doubt of their abilities, or even someone who makes up answers without actually knowing if they are true or not. Fear is arguably the opposite of confidence. Is it though? What causes fear isn't the opposite of what causes confidence. Can you even cause confidence? Or is it hereditary? Can we throttle confidence, or is it a toggle? I think it's a toggle, either you're confident, or you're not. You can't be "kind of" confident. Most would disagree, but words are words, and confidence had a definition, and that would be, "A feeling or consciousness of one's powers or of reliance on one's circumstances", which is the Merriam-Webster definition, which I could argue all day with whoever writes their definitions, or from Oxford, "A belief and an assurance in one's own abilities (self-confidence) or the abilities of another", which to me is a little more accurate, even though I could argue with them just as much. I would define it as "The assurance of one's ability". Fear is caused by an emotional trigger, or repetitive experience, like not knowing the unknown, and is triggered by a subjective perspective. What I'm trying to get at is, you can have confidence, and fear. Doubt would be the best runner-up for being the opposite of confidence. Having doubt in yourself would be more accurate.

What is a good balance in your life? Like, food you enjoy vs. food that is healthy for you. Would you sacrifice enjoyment for health? Or would you sacrifice good health for some enjoyment. Eating healthy is a tricky one, because you can eat healthy and sit on the side wishing for that chocolate bar, or you can just have the chocolate bar. For a quick mind experiment, imagine this. You're sat down at a table with the choice of the same healthy salad that has everything you need for nutrition, and that's all you can have for the rest...
