You don't always need an investor to start your business.
There's nothing wrong with thinking big. But when you have a big vision that outweighs your current finances, don't just sit down and only think about that big dream. Break it down to its simplest form, understand the fundamentals of it, and begin to work your way through it until you achieve that big goal.
This means that if you want to start a business and you're thinking of building a million-valued business but don't have enough to start, begin with the small you have. Break that business down to its core. Work within your capacity, and build it up until you reach the higher volumes you want.
Don't let your dream scare you off. Thinking big is good, you really have to think big, but anytime you think big, break it down to its core. This is first principles thinking: break it down, tackle it bit by bit, work your way through it, and grow with it. Grow while the business itself is also growing.
That is one of the best ways to achieve the bigger goal you want. Don't just sit down, hoping and praying that somebody will be your destiny helper and invest in your business. Sometimes, you need to work your way through it until you get to that bigger picture you want to achieve.
And sometimes, you might not even need money to start. Understand this, sometimes all you need is someone to trust you, and that's a value only your character can buy.
