I think regrets are one of the WORST feelings to be weighed down by. The very word implies a past event that has already happened but you are STILL thinking about it yet unable to change a thing about it coz we can never change the past. Since there's NOTHING you can do about it, what's the point of harboring regrets? We can only decide whether we wanna repeat our actions.
So if you're regretting something you said or did, it's best not to dwell on it. Living in the past can be a dark place to hang out if you're filled with regret. It's more important to learn the lesson so to speak and just move on. If you've made a mistake, don't beat yourself up over it. We all make mistakes! Even what seemed like a HUGE problem in the past from bad grades or being caught by your parents for being super naughty, seems to be things we might even laugh at today.
Time has a funny way of healing wounds and it moves so swiftly. Every second ticking by signifies the passage of time and what amazes and almost scares me is how it will never be the exact same time again when you glance at your watch. Moment to moment, the present keeps changing. It's easier said than done following my own blog mantra "live the moment" but when you think about it, that's all we have right here, right now. It's always THIS moment! so don't look back or too far forward. The moment is right under your nose! :)
