I found this article so incredibly valuable, purely because this has been something that I've always struggled with. Running & co-owning 2 companies for 3+ years now, you'd think that I'd be able to delegate with my eyes closed, yet that's not close to the truth...
In both companies, we have amazing teams and whilst we delegate a bucketload already, we're not quite where Derek suggests just yet. Definitely something to improve on this year.
