I actually regret being exposed to the startup world at such a young age of 17/18. I became totally obsessed with everything startups, especially the stories of newly christened millionaires at ages not much older than mine. I eventually began setting some ridiculously lofty goals for myself that I've failed to meet time and time again, and it's contributed heavily to my often feelings of failure and low self-worth.
So how about this: Instead of rushing to do something before a completely fabricated deadline, chase opportunities with the intent of trying your best and the understanding that no one event or missed deadline renders you a failure or means that you've missed out on life.
