Your question really cracked me up...very funny!
Just to add on the presented responses to your question, this is what I have noticed:
* Most people fail to raise money because they fail to pass the Test of TRUST. Financial investments go hand in hand with trust which is earned in various ways.
During a fundraising presentation, prospective investors or funders ask some very common questions such as:
-Can we trust this company to get us a return on our investment?
-Does this company hold any tangible proof in the form of a VISIBLE product or past sales or purchasing orders, or past customers reviews?
-Does this entrepreneur show concrete work ethics worthy of our trust? (this is a very important question because most investors will not invest in someone who is lazy or with someone who only works 4 hour a week in his/her company)
Once an entrepreneur fails the test of TRUST, he/she can kiss goodbye any prospect of investment.
*Like you said in your question: 'some people churn idea after idea....'
Well, one of the golden rules of investment goes like: 'do not buy into an idea but buy into a tangible product'.
Ideas are unstable but an idea translated in a tangible product shows work ethic, stability in vision (something that investors want) and it commands a certain level of trust.
* And finally, many wannabe entrepreneurs don't raise funds because they lazy! That's plain and simple. One good way to measure laziness in fundraising is to compare the schedule of the successful fundraisers with the schedule of the failing ones.
You will notice that successful fundraisers move into 20 meetings a week to raise funds while the lazy ones may only use a one page social media on the internet.Such lazy entrepreneur should not expect a dime.
