If it isn't possible to predict the future so why do we even try to?
We can't. When you make a choice make sure its the right choice for the present. People say you shouldn't regret doing this because at that time you thought it was the right choice and you tried your best then.
But I think that's also nonsense. The reason we make choices in the first place is to better our future selves. That's why it's so hard. Regret is like failure. You failed to make the right choice and now you are suffering. That's why it is so painful.
But with what you know now, you fix your present. Your right now is what matters the most and the only thing that you can control. Use it to help your future; but if your future self thinks that what present self is thinking and doing is rubbish, future self will change it and fix it. Regret is like crying. It does not fix the problem. Do what you want to do right now. The present is called a present (a gift) for a reason.
