Unfortunately there are a lot of unsolved problems in my life - and in my mind. :) But I think what matters is whether you do what you can to make things better. This is the responsibility. Not if you succeed or not, but trying. We are humans, nobody is perfect and nobody is always successful.

In my experience when there is a choice to make usually the harder way turns out to be the easier one in the long term. Or the other way arount - what seems to be the easy way turns out to be the... well, bad one. I try to keep this in mind.
