Running a business definitely goes in my top 10 toughest things to do. When at the bottom it can be tough getting support. When at the top it's tough to tell people "No.". I've learned that focus, determination, and wisdom can help a business become successful. Focus on the tasks and goals. Focusing may require you to turn down certain deals but will help you stay on track. Have high determination when running your business. Don't quit because something didn't work out. Learn from it and press forward. Lastly, use wisdom. Every deal that comes across the table may not be a good one. So use wisdom when accepting deals. Don't allow desperation to steer you in the wrong direction.
