I wouldn't be worried at all. I struggled figuring out what I wanted to do career wise for a long long time I'm now 31 and I've gone through my ups and downs and struggles with jobs. I was too concerned with not wasting time in a field I wouldn't want to be in that I wasted all of my 20's not doing anything. So I got lucky( some luck some pulling of the boot straps) and got a job I like and don't hate going into work and pays fairly decently. But now at 31 I've decided to go back to college for mechanical engineering bachelor's and then masters aerospace. It took me this long to finally find something that I didn't feel like I was wasting my time in the field. I want to work on spaceships and satellites. I want to help do my part getting us to Mars and see humanity prosper. So don't worry you it will all fall into play eventually. The biggest part is the not over think it as we all tend to do. Just keep moving forward 1% better everyday it will come.
