I think it's important to get a good mix of theoretical and practical skills to be a good marketing specialist.
A formal education in marketing obviously looks better on paper and gives someone interested in marketing more resources and training, but if the creativity, drive, and investigative skills aren't there then all those qualifications won't carry the weight in making their performance as successful.
It seems discouraging when someone has the attributes, some of that education and still can’t get a job because they lack experience. They just need a chance to prove themselves and show that they can make things happen. There are so many ways and places a marketing specialist can be used too which, again, make it such a diverse and open-ended role with high demand with great potential for success all around.
