Some things truly are once-in-a-lifetime opportuntities and when they're gone, they're gone. However, most things in Life have a funny way of coming back around again; although often disguised as something completely different.

Learn from it
We're here to learn lessons. That's why there isn't just one thing to learn, in one single way. Events and people come into our lives over and over again until we "get it" so why not help it along? Pay attention. Ask "what went wrong to make me miss the opportunity in the first place?"

Is there any salvage?
Is there anything we can get from the "wake" of the opportunity? Just cause it passed us by doesn't mean it's absolutely too late. Perhaps the opportunity is still close enough that we can "catch it" if we hurry. It's like hitting "redial" on the phone while the number is still fresh in memory.

Fix the flaws
Knowing why we were late still doesn't bring back the opportunity. If there's something we can do to better ourselves, we ought to do it. That way, the next time (if there is one) we'll be more ready.

Move forward
Once we've figured out what went wrong, it's time to stop dwelling on the past. That event IS gone, so let it be gone. Seriously, all that talk about "crying over spilled milk" is right, "The one that got away" isn't ours. Let's put your focus on catching the next one.

Give it all you got
Live passionately and with purpose; otherwise, it's just a life of regrets.

For me…
I know in my life, I've missed a number of opportunities. "Gurustu" came and went a couple of time because of them. It's why I'm so focused on it right now. If there are second and third chances out there, I'm ready to grab them!
