I think it's really important for us to step out of our comfort zone from time to time and try something new. It's always interesting for me to see this in my students. When I teach younger students, kids really, they are so keen to try something new that you can't really finish your lesson because they're chomping at the bit to get started, but older students can be reluctant to try new techniques once they've learned the basics. I know that I struggle with this at times. Experience certainly brings its fair share of failures and sometimes this can make one afraid to take on, well, new failures. It's important to keep working at those new challenges until we get things right, even when it is frustrating, and finally getting it right is very rewarding.
Perhaps that's one of the most important lessons that I've taken from this first year of grad school is to keep driving towards a goal, despite the setbacks. One of the things that we are required to do is submit to at least one national show each semester. I always send my submissions off dreading the rejection email that I know is sure to follow, but knowing that working hard on developing my ideas will eventually lead to success, so it's important to keep going and not taking rejection and failure too personally is important.
