I genuinely think that trying to overcome your anxiety and stepping out of your comfort zone by doing things unusual to your routine is the main key to success. 
Within your comfort zone, there’s little stress, no action and thus no progress. If you are not challenging yourself to learn, grow and try new things you are never going to see progress in yourself. Indeed, I’m not telling you to push yourself to be productive hundred percent of the time, but its important to remember that putting ourselves in uncomfortable situations can push us to achieve goals we never thought we could. 
Taking risks is what helps us grow, since trying to explore new things makes us even more creative. 
Do not push yourself too far when you are a beginner, as you’re not familiar with the pressure and it can overwhelm you. However, it is worth bearing in mind that stepping out of your comfort zone even once makes it easier and more likely that you’ll do it again.
