It's so overwhelming

As someone who wasn't blessed with a passion that they always wanted to follow and therefore doesn't have a clear idea of what to do in life, I'm extremely overwhelmed. I don't get how I'm supposed not to be. This world offers so many opportunities, but to succeed in any of them we are supposed to pick one and run with it without looking back. I mean, there are some gifted people who can do well in several realms, but most people are (really) good at just one thing they end up dedicating their life to. Just the thought of dedicating my life to one single thing while the world has so much to offer is crazy to me. At the same time, I don't want to be the jack-of-all-trades-master-of-none.

Is there an other way to look at it? Am I thinking wrong? I would appreciate any insights on this.
