There is only so much you can tell someone how something can improve, and I find it a much more effective technique showing them and doing it with them, and explaining the benefits that they can get. Take the following white board exercise for example (text has been blurred on purpose).
From this…
to this…
and so much more to go!
Maybe you could better spend your time getting better at:-
a) surfboarding
OR
b) skateboarding
🙂
Hey, you forgot c) snowboarding which is much closer to whiteboarding, but I at least get paid to do this… 🙂
