The Startup Therapy Couch™: Keep calm, startup on.
What is a startup-er to do when things go awry? Run for the hills? Shut the whole thing down? Shred one's towel and throw oneself into the abyss?
Oh, nay, nay. Don't panic! There will be snags and things will go sideways from time to time. If you realize this from the beginning, you'll set yourself up for success when the unexpected happens. But even if you've been blissfully following your perfectly organized 5-year plan, and you're thrown for a loop by an unforeseen circumstance, fear not.
Above all, communication is your best tool. Communicate with your staff, advisors and mentors about what happened and how to get it back on track. Communicate with your customers to make sure they understand what to expect going forward. Communication is always the key to ensuring maximum success, regardless of the issue or snafu.
Don't panic. Keep calm. Startup on.
