You don't get paid for what you think, you get paid for what you do.
More precisely, you're valued for what you've done, not what you've thought or felt.
This applies if you're an agency, consultant, individual contributor, manager, etc. This also applies to friendships, family, and intimate relationships.
Stop talking about what you're going to do.
If you talk about anything, talk about what you've done.
Cut the excuses. Cut the philosophizing. Cut the over-analysis. Cut the over-preparing.
Stop thinking about what you're going to do.
Start completing what you set out to do.
