Every function is indispensable and people seem not to understand it. I have found out what ever you do as a business or career pays . At first it may look not promising but people want to see you prove your passion for it and you have demonstrated excellent spirit, you will be marvelled the post you will get. Meanwhile your ambition you must market/promote people won't do it for you.
However, if you can't push your dreams alone why not pattern with others.
For professional advice @dobartim is 24/7 ready and willing to assist after all he mentored me and he's mentoring.
Be original and be the best you can.
