Pressure
Think we are rather stupid if we think its easy to be ranked amongst top 10 in whatever we are doing in life, What?! are people absolute stupid and think its all funny time travelling all over the world to smash a golf or tennis ball.
what do you wanna accomplish ? ask yourself that every time you wake up and when you go to bed the same day, ask what you did during the day to get closer to that goal.
sure if you wanna be a sofa comfy land lubber who is happy with a firm steady result and a life of 50 years working 9-17 job then count on the result being rather dull.
