Make 2 lists:
One for cool projects you've had.
One for projects you almost had.
That second list will most certainly be cooler.
Not only will it be cooler, it will even a bit painful and heartbreaking. I'm extremely grateful for the list of projects I've had and currently have, but it's difficult when thinking about my second list to not dream about the swimming pool lined with unicorn bone or collection of priceless vintage guitars that I would've splurged on.It's not just about the work or money.
If I didn't remind myself that there's countless factors that help determine if you're awarded a project or not, it wouldn't take me long to find a padded cell with my name on it.
