Wow- that's a loaded question. There are actually a lot of challenges. Giving up your weekends, long days, heavy equipment, traveling alone, never-ending editing, quickbooks. But I think the most difficult thing for me has been balancing my business/passion with who I am apart from that. It seems extra easy in this profession to lose sight of anything else that matters in life and give everything in you to following this dream. It is super rewarding thus super addicting. I have had to be very determined to set aside time to focus on my marriage, my friends, my family. It's not easy, I struggle a lot. So that would be my answer.
