You're going to be making a lot of life decisions when you're finished with school.
Many people choose to go to uni, many choose to go to tafe, many choose to work, many choose a professional sporting career.
Now people say that you should make a clear choice and stick to it, and that you shouldn't be a drifter. While that may be true, sometimes you'll just have to experience many random things in life (part-time work, travelling, learning new things in general etc) for you to realise what you're truly capable of in order to make that choice.
Even if you realise in hindsight that it your decision wasn't optimal, just take it as a learning experience, and hopefully come up with a better plan. We've all done something we regret haha.
