Wealth comes from hard work but not because of hard work. Wealth comes because of God. Everything is His.
If hard work, integrity, thrift, and perseverance have caused you to succeed, then you don't owe anyone an apology for winning.
My children were taught at an early age how money works and that it comes from hard work. They've been on a commission - not an allowance - since they were little. They learned that if they worked around the house, they got paid. If they didn't work, they didn't get paid.
The only reason to go into business is to make money. You have to work hard at it. If you're not passionate about it, you'll burn out so fast that it is incredible.
