When you’re constantly learning new things, confidence can take a big hit. Make sure to give yourself some continuity. Did you stop doing something (playing an instrument or a sport, reading a favorite genre, etc.) that you enjoy? When learning new things, confidence often comes from success at meaningful tasks: remember to note your successes and reflect on what they mean to you personally. (Succeeding at meaningless tasks doesn’t necessarily increase confidence.) It’s also human nature to focus on failures and forget successes. Did you fall down? Don’t forget to count getting back up as a success.
