Tomorrow I start a new job - still at the same company, but it's a better job with more responsibility and a bit better paid. I'm nervous about it tbh, but at the same time excited.

What I'm really worried about tho, and this is going to sound odd, is the fact I have to train my replacement to do the job I am leaving. What if I don't teach him well? Will there be enough stuff for him to do? Will I get on with him?
