I don't think a day goes by where someone doesn't ask me “Dan, how do I start a business without money?”
I can tell you right now, DON’T.
The absolute worst time to start a business is when you have no money.
A business needs time and money to grow.
So not only will business put you in a worse off position financially, it can take many years for a business to become profitable.
If you're in that position, get a job first, then use that money to invest in yourself, and develop a high-income skill.
Then once you’re making $10K per month and have done for 12 months, you’ll be ready for business.
