The core fundamental of business growth is the owner himself.
You may try the most sophisticated tactics or getting a huge budget...but nothing will work as well as the never-ending improvement of you and your team...
If you want to grow your business you'll need to constantly shed your old skin and recreate yourself. Because what got you to 6 figures will probably not be what will get you to 7, 8 or 9 figures.
Every new stage requires you to level up.
