It's hard not to be "all in" at Narrative Science, and though I am 100% committed, sometimes I struggle with balancing time outside of the office because there's an ability to be connected at all times.
Along the same lines but in a different sense, we are all very passionate people who care about our future and the technology, so at times there are meetings with many contributors rather than smaller groups making decisions. On one hand, this is really great because everyone is involved and gets to have a say. On the other hand, it is difficult when things are not executed on as quickly due to lack of buy-in, or the resistance of not including all possible stakeholders.
At the end of the day, these aren't deal breaker items, though they are honest personal struggles of my own during my tenure.
