If it's not, then it has a very similar message (I'll quote a bit):
Quote:
The pain period is that initial period of time where you really suck at what you’re doing, and every reptilian instinct is telling you to run away to some place safe and familiar.
“Retreat! Abandon the plan! It’s not worth it!”
Most people don’t live their dreams because they bow out during the pain period. They can’t see beyond it. The short term gratification and relief of quitting is more tempting to them than sticking it out and hopefully reaping the big rewards down the line.
But I have to tell you, as someone who pushes his comfort zone quite a bit and is no stranger to the pain period: Sticking it out is absolutely worth it. Even if you don’t end up getting exactly what you want, just growing familiar with that pain period and learning that you’ve got what it takes to make it through the gauntlet, that’s invaluable.
