You gain courage by taking action even when you are scared.
You gain confidence by taking an action even when you are doubtful.
Courage is not the absense of fear but the ability to overcome the fear.
Confidence is not the absence of self-doubt, but the ability to overcome self-doubt by stacking up small wins again and again.
The more competent you become in a topic, the more you gain confidence in that topic.
The more confidence you have, the more courage you will have to take chances to pursue what you love.
The more chances and risks you take, the more chances that you stumble upon better opportunities.
The more opportunities you have got, higher the rate of victories.
More victories may result in better life, respect and wellbeing.
