Your apprenticeship will be very rewarding, even if at times it may seem demanding. Once you have finished your apprenticeship, you'll have a world of options open to you. You may be able to carry on working in the same place, or look for a similar job in a different company. Having industry experience is very important when getting your first job, so being able to show that you've got that plus qualifications will give you a huge advantage over other applicants.
Also, your apprenticeship may have showed you other interests that you never knew you had, so think about going to uni or getting another qualification. Or, take some time out to think about your next step, and look into taking a gap year -you can work abroad, volunteer or just travel.
