And the fish said "blub"

Am I drowning? Or just swimming to fast?
As you know, I’ve started teaching in Language School nr2.
Then all of a sudden, last week, Language School nr1 contacted me again, after weeks and weeks of silence. So as from today, I’ve started teaching there as well. And in between are the first private students announcing themselves.
Every day feels like “the first day @ the new job”, ‘cause then it’s a new school, then it’s a new student, then it’s a new group, etc. And although it’s all very exciting, and I’m having a really good time, I’m also spending loads of energy on just staying focused. Staying focused on controlling the stress. Staying focused on feeling self confident. Staying focused on, well, just not losing myself.

Day after day, I keep on telling myself:
Yes, this is what I want to do. Yes, I love teaching. Yes, the financial aspect will work out in the end (just keep on living of your savings for the moment). Yes, the administration is a pain, but you can do it. Yes, you are good at this, no need to stress. Yes, you've made the right choice. Yes, you can say “No” if you want to.
And once again : Yes, damn it, you've made the right choice.

As if to test that, I got an email from an old colleague in my mailbox today : “I have a great project and I really really see you working on it! Give me a call asap! I believe you are THE person for the job”. She was international sales manager at my previous company, and we got along well. She left, and, together with another partner, started her own HR company. That company was on my “to contact-list” in case I‘d decide to keep on working in HR. And now, exactly one week after I made the choice to teach again, they contact me. *Sigh*.
I never knew that making a career change would be this challenging...
