I try and discover the positives in all I do. There are times where this is difficult, but I still focus on it. Sometimes I forcefully need to remind myself of all my existing blessings and that usually carries me back to the right mindset. Regret is grievous if it freezes you. If it makes you believe all is over. I like to see it differently. If it's significant enough for me to regret, it's valuable enough for me to reach for it and try again. I would regret not trying more than failing.
