Let me describe flappy bird. Flappy bird is a game which is very popular. You have pipes to pass through. So for my argument, we need to understand that in flappy bird, you go just in 1 direction, which is going straight. In life, you need to manage when to go straight, turn or retreat. You can't live with just pushing forward. How is life a game of flappy bird? It is not!
