The specialized training, knowledge, talent, creativity and guts to design successful advertising comes with an idea person, not a software program. Either learn the basics of designing advertising that sells or hire people who do. It's not as big a deal as you might think. Ego and advertising don't mix well. Focus on the profit angle, research and testing - it's the only thing that counts.
Bad advertising can un sell a product.
Therein lies the danger. Bad advertising can hurt you. They are seldom the same. Learn the difference between what you might personally like and good, solid advertising that sells. Your marketing program will achieve a much higher level of success when you do.
