The Vine or the Wine?

I've always wanted a vine in my garden. Don't ask me why. Flowers, well, they're nice to look at, but they're not great to eat. Vegetables, that's the way forward. A vine, well there's something about the long term nurturing and the reward of some fruit each year. And grapes don't get nicked by the birds like strawberries do.
However, the wife has always told me - not in this house dear, we won't be here that long...
So, now we've been here 9 1/2 years I've put my foot down and planted one. I don't know if it'll even survive, let alone whether we'll ever get fruit off it. I'm going to enjoy trying though as it gets slowly trained up the garage wall. But, even if it doesn't fruit in the first 2 or 3 years, should that stop me planting it? What about the next owner, and the next? The oldest vine in the world is at Hampton Court, planted in 1768. Thats a lot of generations that have benfitted from its fruit.
And, yes, all this got me thinking. So many seem only to think about the short term. It's all about the fruit, and in this case perhaps the wine - what gives pleasure now. Should I only be concentrating on things that have an immediate result, and those that benefit me? Well, clearly not, else I wouldn't be doing youthwork. Maybe there isn't much excitement about tending vegetables in the garden and reading bedtime stories to the kids, but what about the longer term investment of these things? Perhaps things of which you'll never see the real results.
