You are welcome and good luck :)

As an entrepreneur, I remind myself to learn something new everyday, no matter it is sales negotiation skill, business partnership development, marketing or new programming language. One thing I learned and I feel this is most important thing entrepreneur should know which is listen to other people suggestion. You should appreciate to those people who gave you advice, because they don't want you repeat the mistakes they did before.

I want to create a car to replace horse. (Just a idea, and car didn't exist yet)

I want to create a car to replace horse.
This is how the car look like, got wheels under the car body, and with this design mechanism, it can burn the oil to energy to move the car. (How it work)
There are x number people are riding horse, and increase y percent yearly. They may replace horse with our car because faster and can travel anytime as long as the car has fuel. The house need to rest after few hours. (Potential market size and competitive advantage )
This is our cost to build a car and target selling price. (Business plan with clear business model)
Now, I need z amount of money to achieve this.

Do you understand the different between "i want to change the world" and "i want to change the world, this is my business plan" now?

Thanks for your input, but personal attack with "stupidity" will make people won't share their thought to you anymore, thanks.

Agree we should creating value that will change the world. But let become a little bit more realistic.

"It's never too early to make money but it might be too late to save your startup when you starting to run out of money." - Matthew Phiong.

Couldn't agree more on Matthew's sharing. No investor will invest to a startup which doesn't have a very clear business model. IMHO, they are not our father/mother, investors are looking at how much return they can get if they invest.

This is Facebook's first pitch deck in 2004, inside the pitch deck you can see that just two months after launching, they already have 70,000 users at 20 major colleges and going to expand to 200 colleges in six months. They also mention that they are going to make money by showing banner ads.

Hi Wei Loon, not everything of course. If you look into my previous reply carefully you will realize I only point out one of the responsibly of the leader is seeking fund to keep the company alive and grow. 

Wei Loon, in the case you mention, it is not co-founder but employee. Then you don't even need to give equity but you need to pay them according to market rate. If you say startup don't have much more money. One of the main responsibility of the leader (CEO or founder whatever) is to source funding to keep the company can sustain and grow no matter you get it from investor, family, friend or fool. Else you can only offer a big portion equity to convince the one you really need and join as co-founder at no salary.

Ya, each party come out 10k and both get 50% seem fair to everyone.

It depend on what stage your startup is. If just in idea stage, I think all co-founders (no matter what role you are playing) should put some money into the company to show the commitment, equity can be discussed as what value-added you bring into this company (programming skill, market access connection etc). If the startup is already running a while, then you just pay the salary or give a small equity from your option pool with vesting.
