Marketing Mistake – Lack of a Focused & Clear Marketing Plan

In my business consulting experience, I have noticed a similar attribute that is common in most entrepreneurs and business owners.  Most are “doers” rather than “planners”.  In reality, being a “doer” is perhaps the ultimate character trait of a successful person.  Rather than thinking or wishing, they get out there and make something happen.  In fact…I would probably put myself in the “doer category”.  Although there is amazing benefits of being a “doer type”, I’ve often found myself that (in the doing mindset) I’ve gotten myself in trouble as I didn’t think things thoroughly through.  Can any of you out there reading this relate to this?
