Life taught me some lessons.

1. Thinking too much does not get you anywhere.
In the battle of waterloo, Napolean hestitated to attack even though he had the larger army, just so the afternoon sun could dry up the battleground to favor the usage of cannons, which he so loved thanks to his family history. Unfortunately, the delay in time allowed the enemy's reinforcements to arrive and subsequently, as we all know, ends a chapter in history's book.

2. Not thinking enough does not get you anywhere.
Personally I don't think there is a need to further elaborate this, since from young, we were educated to think before we act, plan everyday meticulously, think out procedure as detailed as possible.

3. After reading the above, first you will 1, then 2. and end up with 3. Which is life gets you nowhere. It would be better to not think about this problem =).
