To have a goal is a wonderful thing.

To wish your life away is not.

A long desired wish can drive you to reach otherwise unattainable heights. To want something so bad that you do whatever it takes to get that one thing can uncover or develop great talents. Practice on the ivory keys can provide many gifts for the player, as well as the audience. Study to achieve academic success can open doors to many opportunities wished for in youth. The wish for a better world opens the heart and creativity of the mind to envision a different way than we have now. All of these things are good and fruitful and honourable.

This tells me the problem is not in the wishing but rather in the picking. The matching of a desire to a realistic possibility is not known to us at the time of the wishing. If the wish is strong enough and there is any possibility of it becoming a reality it can be made so. But when the wish is fanciful and not in the reality of one's life it is the root of much despair and a wasted life.

To wish you were here with me is a wish that is not to be realized in this world. I just wish I knew how to quit wishing it.
