Right brainers feel things much more deeply than most other people do. It is trying to verbally communicate those feelings to others that is the challenge. That is why they create, to express what they are feeling through art. So maybe that is not a bad thing.
Right brainers can be impulsive. That live-for-today attitude and ‘being in the moment’ works for the artist in them, but to succeed, they have to give some thought to the future. There can be long term consequences when they play now and pay later.
Divergent thinkers often go off on tangents, and are frequently seen as scatterbrained. It is hard to concentrate when your are not inspired or interested. It takes discipline to get started and stick with the business side of the creative business. Creatives can work harder than anybody if they find something they love to do. They just have a hard time learning to love math, taxes, regular business hours and client follow up.
