Who I am as a designer

I'm at a time in my design career where I feel as though I need to specialist in a certain area of design. I feel like i'm a 'jack of all trades' in design and it's hindering my work. I think my best route would be focusing on digital designs as I am not confident with my drawing or painting etc. I could then utilize screenprinting more if i wish to create more personal works. I would like to create a typeface as I believe this fits my strengths well, as I am good with ideas, working technically with maths etc.
