Whether we are in pursuit of a goal or just everyday routine events, we can both, suffer setbacks and enjoy small victories. The thing to keep constantly in mind is not to dwell on either but instead give yourself a minute to get your frustrations out or a minute to celebrate. A small win or loss should not deter you from your work for longer than a minute. Any longer and you lose valuable motivational energy, not to mention precious time.
When the moment calls for a larger celebration or show of unity and support, you will know it. Do then, the emotionally and spiritually responsible thing in both those situations and be extremely grateful again for everyone and everything you have.
