While it's true that you may be a bit scared, I hope you all chose CONFIDENT! You have put in so much work to discover yourself and which careers best suit you. Be proud of that, and be confident in your choice.
Sometimes, if we don't get a job right away after the first few interviews, we humans tend to get discouraged. Stick with it my friend, I promise it will be worth a million bad days when you DO get the job:)
