One thing about being in a job role that was not for me, for ten years,is that I realized how much time I was wasting.
What I also realized is that I was wasting everybody else's time too. While they felt like they were grooming me for the next role, I secretly wanted something else. No, I did not share this because I needed the job for the money.
What is the alternative? Stop bullshitting yourself and others. If it is difficult to make a drastic move then there is always baby steps.
My move was drastic but the goal was the same: It's time. Today is the day. Today might be the day to enroll in that class, call that mentor, quit, or get fired.
It only takes one decision. There will be many decisions after that but the first one is the one that will start you on a new path.
....or do nothing. I can guarantee that tomorrow will be exactly like today. The yearning will continue next Tuesday. The following Monday will be the same. In all, it is just wasted time.
