Yeah i had a side hustle for several years, and found lots of the work quite rewarding (especially in the intellectual fulfillment sense). But if there is anywhere that i suck in life it's leading sales. I'm pretty good as a second banana to another sales lead...but since I ran a one-man show my sales acquisition record for my side hustle was abysmal - even though my existing clients at the time loved me! :-)
But, yeah i considering starting something up again but maybe partner with someone better at sales.
