Never stop learning. Find people who have done what you want to do and learn from them.
How can I grow my business?
Never stop learning and also learn from experienced people. Make your goal and concentrate on it.
For growth to make sense, it needs to outpace the overheads so that it doesn't cripple the margin of profit.
The worst spot I find many businesses, is during the growing pains stages. They grow, not fast enough to hire quality help, but fast enough to have everyone stressed and overwhelmed!
