You have the most important skillset to sell on here @mawit07 and that is yourself.
Being genuine is the most important thing anyone can do on here. There are a lot who come on here and pretend to be what they are not. I am not a professional writer yet I put up posts each day that people seem to enjoy. I provide my honest opinion based upon the research that I take time to do.
That is all I can do...be myself.
