I am in the same boat as you. I am 19 years of age, completed a Diploma in Worldview last year and am now training to be a teacher.
I had considered teaching for a while (mainly because I come from a LONG line of teachers) but had decided that I didn't want a 'normal' job and be stuck in a classroom for another 30 years. But after spending a year looking at possibilities I decided teaching was a fantastic route to go because:
-it is a job that is needed anywhere and is used in every situation.
-teaching does not just mean classroom teaching. It may lead to outdoor education instruction, training colleagues in different skills etc. In many situations you will use those skills so it is not a wasted degree.
-you are in a prime postition to positively influence people, and it is a job where you will see results.
-if you look at many people who are in very influential leadership postitions (government, business etc.) many of them started out as teachers. Teacher training provides fantastic organisational and social skills and gives you a valuable field to build up contacts. It leads onto great opportunities.
-teaching offers variety: Different subjects, different students, class trips, a chance to be creative in the classroom etc.
I don't plan on teaching long term, but I realise that it is a good field to get into as plenty of jobs are available and it leads to good opportunities. So rather than viewing whether teaching is right or wrong for you, focus on the fact that studying teaching (even if you don't end up teaching in a classroom) will never be a waste of your time or money as it equips you with valuable life skills.
I hope that helps you with your decision.
