When I start having a regret, I actually question why its a regret. Is it something that I can change now? Is it something that needs closure? would that help me or others involved? If yes then I will try and 'fix' it.

However, a lot fo the time I need to remind myself that regrets are pointless. Every decision, step, commitment I have made in my life has got me to where I am today. I have in most cases learnt from the things that I regret from time to time and so long as I acknowledge those lessons, and make sure I dont repeat the past.

If I am not happy in my current situation and I am regretful of the decisions I have made then its time to re-evaluate and move in another direction.
