There are countless examples in the business world of once-successful companies going into businesses that they know nothing about, only to fail simply because they were successful in their first venture. Confidence is important but the care must be there too. Another important key is to keep your priorities in the proper order. You may be successful in business, but if you fail in other areas of life and in relationships with your family, friends, with the Lord, then no manner of business success can make up for that. Thus we must never lose sight of what is important.
Money can be misleading.
Money does not buy happiness. It can help in some ways, but it can never make up for the things that are truly important like family and friends and relationships. Miracles can be performed by hard work. The key is getting your priorities in order and fully dedicating yourself. You also have to realize that you can't do it all yourself so you have to select and attract outstanding people.
