Below is a piece of advice I wrote for myself at the beginning of last year (2015). I still struggle with this (and surely will for a long time), but this will be especially helpful to keep in mind during my time at MakerSquare.
Continue to do the best job that I possibly can, while maintaining a little more emotional distance from it. Fretfulness and anxiety doesn’t breed effectiveness. Give it everything, constantly solicit constructive feedback, adapt… but forget the rest. Don’t let it take over. Maintain balance.
