Join a startup accelerator: Another great option is to apply to a startup accelerator like Y Combinator, 500 startups, or TechStars, where a group of investors will help coach you, connect you with potential partners, and provide startup cash in return for a small stake in your company. The competition is tough to get into these, so don’t rely on them as your only path forward.

When an airplane leaves from one city to the next, it has a plan. Its plan is called a flight plan. It's a massive action plan that involves speed, altitude, direction of travel and many other facets. But what happens when there's turbulence or air-traffic congestion or it needs to change course for some other reason? The plane changes its plan. But it doesn't change its goal of where it's going. Create and follow a plan, and don't be afraid to change it if you see something isn't working.
