Many entrepreneurs are cash strapped at one time or another and we all have financial obligations that need to take priority so even though I don't know your skills and experience you could do the following...
1) start freelancing or consulting, use Clarity to promote your services
2) take a below-market salary at an existing startup and prove your value, maybe you'll get some nice stock options
3) start an ecommerce company - there are plenty of products, distributors and manufacturers you can find quickly online so whether you're selling candles or headlights or jewelry it's quick and easy to get started...perhaps they'll even do the dropshipping for you.
