Ask HN: Fired from a company I loved- seeking advice

As the title describes, I was fired from a company I loved and am seeking advice on where to go in life and career. Background: I joined a late stage startup that I absolutely loved 3 months ago in a sales/business development role. I immediately fell in love with the team and the culture there and piled myself into the team and in my role. I quickly performed well in my job so my problem didn't arise there... In my final month in August I managed to pull 60% of my small team's results as well as literally 100% of the final results in a higher priority campaign. Unfortunately, it seems that my downfall came from being too eager/open/stupid in challenging some ideas from one of the founders. I had the idea that it's fine to challenge the status quo or to challenge ideas for the sake of coming out with a better idea in the end. Perhaps this isn't how people on the receiving end felt when I debated (read: argued) with them about the right decisions to make. I truly thought I was doing what was in the interest of growing the company but in the end I guess I failed in recognizing the damage I was causing. It's like a bad break up- I was in love and now it's gone. I'm now at a point where I need to figure out what to do with my life next. Should I figure something out for myself? Should I go travel and explore a bit (may be hard with student loan burden)? Should I jump immediately into my next job? Any comments or suggestions?
