As a Liverpool fan I have lived with this for all my life. Consistently inconsistent. The team and the players have showcased this for the last 15 years, especially players such as Heskey, kewell, Smicer and even Suarez nowadays. Weapon he champions league but were shocking in the league; then great in the league soon after but rubbish in the cups. As a Liverpool fan one thing has remained consistent, my support and belief that "next year will be the year".
Another example of consistently inconsistency are the trains. Overground, underground, around and around. When it snows or rains there are delays; hot sunshine = delays. This doesn't happen everyday but it is still annoying and people rage, sweat, moan and cry about it.
With all this unpredictable nature of life, one thing we need to do is to try and enjoy it. Be happy with life and do what you want, spend it with family and friends and always look out for each other.
