I'm going to keep this short because I'm heading out
Social gameplay- I talked to people before I did anything, and I made personal connections with people. I mad sure that I was keeping up with what was happening, and I put my input in whenever it was needed. I was playing for myself, and I knew I needed to do that.
Strategic gameplay- I think my strategic gameplay can be viewed in my alliances. I was loyal to the people I knew were going to be with me, and then when I found out about other plans, I cut ties before anything could be done to me. I didn't just go "oh hey, this is an easy tribal" Tribals were never easy, and there were a lot of difficult decisions, but ultimately things had to be done. The way I voted was to help me get here. There were certain people I wanted to keep around because I knew they'd be targets, so it might take the pressure off of me if I felt in danger.
I did pretty good in the challenges. I won a few, but I know I put effort into all of them because, it may be hard to believe, but I never really felt safe.
But, I think I owe my spot in the finals to luck. Getting the idol at the reward really helped me out, and it helped my alliance claim majority. And then the auction was the ultimate display of luck. I was safe from tribal, and I had an idol. But sadly my two closest allies had been taken out of the game, so I needed to go on a string of immunity wins, and if I hadn't had immunity, then I had my idol. The f6 tribal where I didn't play my idol was probably the most nervous I had ever been in the game, but I just felt like I would be wasting an idol, but I wasn't the target and I got safety from another round.
In conclusion, I didn't play the best game, but I played a good one.
