My mom gave me some sage advice when I was young that still holds true in every part of my life: Start out the way you plan on holding out. I didn't fully understand it at the time, but the older I get, the more it rings true. You must come to the table as you are from the start.

Support your sister's vision but not at the expense of your own. That's the only way you'll remain motivated and joyful throughout this transition. I would suggest you and your sister have a heart to heart where you negotiate the level of support you feel comfortable with. What I know is that the excitement you feel at the idea of the business will transition into the realities of running it. If you start out of the gate with the realities, you'll be the better at the end.

I would love to have a consultation with you, free of charge to help you navigate the ambivalence that you feel and to help you get more clarity. I truly believe you can approach this in a way that both she and you can get excited about. Contact me.
