We all have voices of self doubt. It sucks. You don't beat the self doubt by thinking about how much it sucks. You beat it by taking action and accomplishing things that make you feel happy. When you know exactly who you want to be and what you want to do you don't care what other people are thinking because you're on your journey with your goals. The same way other people should be on their own journeys. Being afraid is fine. We all get scared, but it's not an EXCUSE. In my experience when I do things that I thought I was afraid of I have realized it's not nearly as bad as I thought it would be. And simply doing the thing I was afraid made me feel amazing even if I was terrible at whatever I was doing. No more excuses. No more complaining. Go take action and have fun.
