One of my favorite sayings: "How do you eat an elefant?" Answer: "One bite at a time"
Yes, you have a bumpy road ahead.
Yes, you have a lot of hard work in your future.
Yes, it is scary to take on such a new challenge.
Yes, you have a wonderful dream.
Yes, you can do it.
I agree with whoever said to find others in your area to partner with or help out. Your sister is so proud of you for drudging on, I bet!
So get out that knife and fork and take that first bite.
