If you were to put your music career desires into your preferred order, what would that be?
Do you have any music industry experience?
Do you have many/any contacts in the biz?
You mention that you post your vids, which in itself is alright but of small use when outside a planned, concerted campaign... do you do any other music biz activities on or offline?
How determined are you to have a music career if you were to mark it out of 10, with 0 being not determined at all and 10 being fully committed, totally determined?
To proceed, you first need to really know what your primary target, and second and third and fourth, so that you can take decisions in the correct context and to avoid being distracted by shiny object syndrom as opportunities present themselves. It also allows you to really prepare so that you are in a position to take advantage to the fullest of the chances that come your way.
You have to have a good and realistic mind set, completely professional in outlook and behaviour to give yourself the best chance. That means organization, discipline, hard work, research and applying your creativity to your music career and the chances you get.
Your answers will help me narrow down any advice I can offer to something hopefully useful to you.
