I love this post Sagi.
I try to never regret anything that I have done or haven't done, as all of my experiences have contributed to the person I am today and I like who I am right now. If you don't like where you are right now then you know what you need to do - get up off your arse and change something. The energies you waste regretting and having self pity are much better spent on something productive. Sure, we all have bad days, but you get up and back on your feet. I say this as someone who has been through a lot of shite. Perception is reality after all.
To me, regret is one of the worst emotions. You can't change the past. You can only change the path you're on at the moment.
I'm 25, and I love my life. I love the people in my life and the planet I live on and all the wonderful things there are to see and do (and the games!). I feel like I'm in the best shape of my life and it feels great to know my hard work is paying off. By years end I'll have my doctorate and I can start selectively calling myself 'Doctor'.
I'd much rather concentrate on these facts than anything that used to get me down.
Good for you! The boyfriend and I have recently stopped smoking cigarettes. We had been quitting on and off for a while and damn did it make us a bit crazy and grumpy. My body is my temple once again.
Oh and happy birthday!
