Teaching is a great profession, but it isn’t for everyone. If you are excessively stressed out by your teaching job on a regular basis, you may want to look into doing something else.
Keep an eye on your future. Do you want to teach until you retire? Do you want to be an administrator at some point? Do you want to change to something totally different half way through? Some things need long range planning, an extra degree, etc. so don't find yourself getting stuck.
Your goals can change, obviously, but it is never a bad idea to be thinking about the long term. If you don’t, sometimes years and even decades can go by before you realize it.
