If you worked the hardest that you could, bringing your most attentive work ethic and trying your best, then there’s no use fretting over regrets or things you should have done, could have done, or would have done given different circumstances. If you always give your best work, then people will take notice. You’re never last place. You can also think back to some of your previous projects and think “yeah, I gave it my all.” You should also think of your most recent accomplishment as your best accomplishment, until your next accomplishment. Each victory builds upon the last victory.
