“It's a challenge on a lot of different levels.”
“This is an unprecedented challenge, but one that I relish.”
“This is a major, major, major, major challenge.”
Accept the challenge and never fear to change.
A life without challenges isn’t alive.
“One of the biggest challenges is lack of standardization.”
“Our study challenges that conventional wisdom.”
“It sounded like it would be a challenge and it really was.”
Not an impossible task, just an outrageous challenge.
Without challenges, we fail to wonder.
