At some point, you'll decide for sure. Until then, explore your options, ask questions, do research, talk, think, listen.
But, if you can, try to do it in your spare time. Because every moment you spend exploring, asking, researching, talking, thinking and listening are moments that other people are spending doing things to better their lives, to get on with their lives, to live and enjoy their lives. Far too many TS persons1 end up spending the quality part of their quality years on this stuff, while their peers are finishing school, working on job skills, making money, setting up a life they want (instead of dreaming about what choices they might have and sifting through mythical options) only to wake up on day and find themselves pretty much alone.
So, for example, you don't want to be the person who is 30 and just starting their third 'entry-level' position and finding all their old friends drifting away because their lives are so far beyond that now. You really don't want to be the 47 year old looking for an entry-level position, you'll find there are none.
There is a very fine line between carefully considering and choosing your options and obsessing your options away. Tragically most people only find out too late they are doing the second. My experience that that people who waited for all their ducks to be in a line, for everyone else to get straight on it, who wait to be sure, spend most of their life waiting. My hippie friends and me used to sing: Sure don't know what I'm going for, but I'm gonna go for it for sure, got a much better life out of that deal, even if they were not sure where the bus was going when they got on it. It's the getting on it and riding - the joy is in the journey - that's the real reward, not the pot of gold at the end.
Time, time, time, see what's become of me
While I looked around
For my possibilities
I was so hard to please
But look around, leaves are brown
And the sky is a hazy shade of winter
1. I took the TS out because this affects lots of people, sadly, several I once knew.
