Well one way to think of the challenge part is a Rocket or Airplane the amount of energy it takes to get business going is so much more for a little reward at the beginning.
95% of your fuel for example is spent on that runway but not going fast enough to gain traction.
Once up in the air the fuel is hardly used at all but going six hundred miles an hour
You need the airplane at 100%
The Hardest part is taking off
An Airplane is only designed to set off on 100% Throttle
It does not take off in first 100 Yards but it’s not until 500 yards that it takes off.
Need to throw it at 100% Throttle to get your life out of the valley of despair and by putting the time in now to be lazy later you can truly be free.
