What do you need to become an IT Consultant?

I think this is very individual-based question. As an IT Consultant you shall be:

1. Well rounded person - technical wise
2. Well aware of the business nature of your customer
3. Well educated and really experienced to think out of the box merely all the time
4. Well mannered and diplomatic enough to avoid your customer's or competitor's raids
5. Well dressed. With a magnificent leather ware, watch, briefs and a pen
