Rephrase this question by taking an introspective look at your own strengths & identifying how you can bring value to the world at large, or better yet, a segment of the world.

I've made the mistake of following the heard, 'shiny object syndrome' & chasing the hottest new industry. Often times, by the time an industry is hot, someone in a garage has already been hacking away at it for the past 5-10 years and they're well positioned to own a large segment of the market share.

Don't chase fads, trends, & bubbles. Be the guy hacking away in at their business and your time will come.

To answer your question more directly, he increase in the number of people starting their own businesses in the US has surged to a 13-year high. People such as yourself perhaps. Solving a need for these new business owners is a massive opportunity. I feel that providing some fashion of digital services to these new business owners is a nice niche to carve out.

Best of luck :)
