One thing I learned from these startup weekends, too, is that it's just one weekend. You weren't necessarily forced or desperate to find a team or co-founder there, especially with it being your first startup weekend-style event. It's just a mindset.
Yeah...it's a great place to meet people, but it's a bit like going to a bar and looking to get married instead of just trying to get a phone number. You're likely to be disappointed if you're expecting a diamond ring.
True... but sometimes I go to the bar just to hook up ;) But your analogy still holds true.
Managing expectations and emotions seems like an important piece to building a startup. Things like pride and ego can help fuel you, but can also get in the way of clear thinking.
