Don't try to carry the weight on your shoulders only. Team members are often closer to the customer and have some valuable insights.  

Ask advice from peers, your advisory board, outside experts and mentors. Keep an active mentor relationship with a few peers to discuss you...

Do not play to your weaknesses when analysing the situation.

See every challenge as an opportunity to learn and provide leadership to your team. They need to view you as a role model for their success.

Don't allow a setback to sidetrack you from your vision. There is seldom one path to a goal, so take the time to re-focus on your vision and find alternate routes to reach it, perhaps using a much better idea than the first.

Ensure to learn from your progress and challenges...

One of the leading causes of business failure is giving up too soon. Building a business is a journey, not a sprint.

You can overcome almost any disappointment if you are fully determined, motivated, and committed.

As you search for alternatives, don't let your emotions overrule your logical decision process.

Instead, use your initial process for evaluating markets, customer needs, and financial implications. Then, allow the challenge to broaden your thinking.
