Well, I believe I could answer this question since I am a graphic designer. Just remember to rephrase this a bit please.
1. As a designer, I have learned that your work doesn't speak for itself, you do. You must show/tell people about your work and how you feel about it.
2. Remember your "Why?". When your at the point of almost giving up, think about the purpose of the project or design.
3. Ask for help. When you need it, always ask for help
