2. Dealing with rejection
Rejection is hard. We want others to recognize our hard work, see our potential, and to invest in us so it's disappointing when that doesn't happen. So, what do you do if you aren't selected? It's up to you how to respond. One option is to ask for feedback so you can identify areas where you can improve. Another is to talk to your mentors and advisors about other opportunities you might pursue. With luck, the next time you'll be celebrating your success.
In life, we often get told no more than we get told yes. It's frustrating and can make you want to give up or change course. But, when you know what you want to do, you have to go after things even when they're hard. Think about what you can do to push past the difficulties and step outside of your comfort zone. Keep doing this enough and it will become a part of who you are. Once it does, you'll be able to do anything.
