"Now I found course offerings that I’m interested in taking in the evening to help retool"

I’m starting this program. I have difficulty finding the extra gear consistently. I tend to rev out of control or circumstances in my life misalign. I recently moved home from a place I loved since I needed room to refocus and find myself, and landed a great job that would allow me to rise to the occasion. Unfortunately, it’s government and unionized and I didn’t respect the opportunity enough. Made poor decision out of personal stress and my compromised my emotional well being. I decided to pull back, ask to switch off the job, and continue work for this company on a less intensive job white I tinker with myself and mend. 
Now I found course offerings that I’m interested in taking in the evening to help retool. My goal is now to work at my current place since it’s a good place to work while focusing on retooling myself so that next time an opportunity arises either at my current place of work or at a new place or I create my own opportunity, I can pursue confidently and fiercely in a manner appropriate for the position and task at hand.
