No, everything I've done has brought me to here, and I'm happy now. The only time that will come to pass is the future. Sure you can think and talk about past events, but you're here now and dealing with you have now.
If you're happy now, then technically there shouldn't be any regrets, right?
If you're depressed now then I'm sure you have plenty of regrets?
This is such a deep question. Not really a knock, but you're smokin pot again aren't you?
