Consider your business as a work in progress. You will always have something to work and improve on, changes to make, cutbacks and investments to decide on.
Give yourself permission to not know all the answers but be willing to find them.
Read and learn even when you feel you are at the top of your game. Stay ahead of the competition and look at where your industry is going. How can you prepare for it? What new products or services will be needed? How do you prepare staff to shift with the times?
Find a mentor and be willing to take their advice. Learn from their mistakes rather than stubbornly choosing your own way.
If you can stay open to changes, you will keep your business positioned to lead and prosper.
