"Men spend their lives in anticipations,--in determining to be vastly happy at some period when they have time. But the present time has one advantage over every other--it is our own. Past opportunities are gone, future have not come. We may lay in a stock of pleasures, as we would lay in a stock of wine; but if we defer the tasting of them too long, we shall find that both are soured by age."
Charles Caleb Colton
When I read this quote I realised I've done it too... we should be happy NOW and live today for today ! :)
