More responsibility

I was offered more responsibility at work and it was the perfect thing to happen for my highest self but the self I’m used to being in the past said “this is too much, this will tire me out, I don’t want to have to be responsible for big things, I don’t want to fail, I won’t be as free.” I felt the effects of those thoughts yesterday and almost did not take responsibility for the rest of that day! Luckily, scheduling my day has become a habit and routine for me so I notice that it brought me back to being responsible for the things I put on my calendar. I wonder though, how does one manage the thoughts that comes with an expanding life? I am perfectly suited to the life I have now, the flow is incredible and I’m producing amazing results for myself, someone noticed that at work and gave me the “opportunity” to stretch myself thin AGAIN…help!
