Good ideas without action are just bad excuses

‘Good ideas without action are just bad excuses.’

I’m not sure if this saying from 2009 needs to be explained, but I will anyway, with an example.

A lot of people say:

‘I’m gonna write a novel!’

but then don’t start writing, they don’t act on their words. So it turns into:

‘I’m gonnna write a novel – when I’ve got a bit more time, after the kids have moved out, after I’ve bought a new computer, after I’ve finished painting the Sistine chapel…’ 

etc., etc., etc..

Hence: good ideas without action are just bad excuses.
