A fellow solopreneur here, I've been doing it for several years now.

I browsed through your profile, website, Twitter account, and I'm still not sure what your product is and what it does. Is it consulting? Coaching? Book?

You don't have a lot of followers (me neither), so tweeting won't get you far as you're talking into a void. Instead, join existing discussions where people already are. Also, don't use too many hashtags - it looks spammy.

Not trying to put you down, just offering a different perspective you might not hear otherwise. I hope you succeed.
