Seriously, Penny Lane.

“I always tell the girls, never take it seriously. If you never take it seriously, you never get hurt. If you never get hurt, you always have fun.” — Penny Lane

 
With all due respect to the immortal Penny Lane of the immortal film, “Almost Famous”:

That’s a load of crap.

Take your work seriously. Work hard. Throw yourself into what you do.

Overcommit to the work.

Yes, you get hurt doing great work. You get pushback. You run into haters. You struggle.

But if you never get hurt while doing the work, how much were you really putting into it?

You have to take it seriously. You have to get hurt sometimes.

Anything else is just work half-assed.
