The entrepreneurial life is one of challenge, work, dedication, perseverance, exhilaration, agony, accomplishment, failure, sacrifice, control, powerlessness... but ultimately, extraordinary satisfaction.
Being an entrepreneur is tough. Really, really tough.
Without question, the single most important attribute of a successful entrepreneur is integrity. And that's not some philosophical or theoretical malarkey; it's hard-nosed fact.
I like to invest in companies where I can really add value from my experience, network, etc., so checking out my portfolio of other investments, and my background, will generally give some guidance there.
I almost never invest in ideas or plans, so you'll need to have a company and at least a product, if not customers.
