I love how a Test can be won or lost either through session after session of hard grind, or through a moment of brilliance or a single mistake.
It feels a lot like life. Sometimes you have to put in lots of hard yards, sometimes things change in just a session, and sometimes everything changes in a space of a few balls. You gotta adapt to sudden changes in a situation whilst also being able to knuckle down and focus for long periods of time. Sometimes you have to resist temptation, sometimes you have to take risks, and sometimes you just sit back helpless and rely on others to take your team to victory.
Sometimes you can spend all day in the field and have nothing happen, only to suddenly be presented a match winning opportunity with just half a second to react.
Sometimes a days worth of hard work is undone by a simple mistake.
Sometimes you have to grab the game by the neck and make things happen.
There is luck, there is hope, there is skill, there is patience, there is determination. You need to be able to seize opportunities, but the second innings always provides a second chance for those who fail in the first. Conditions change, the mood changes, the requirements of you change.
It's just such a great game in general.
