A mentor is a great addition when doing anything new. SSomeone to guide and advise, to answer questions, to be realistic and stop you from jumping early, and perhaps someone to talk to about oblique issues. I'd also recommend (without knowing what you already do) good food at regular intervals, ensure you have and are able to stick to basic routines, don't drink alcohol, minimise bread and pasta intake (no need to stop it completely), walk where you would previously get a ride, plenty of air and water (same as for dogs and cars) and to return to the start, if you can't fin a mentor then try ensure you have people to talk to and with, especially offline.

And don't worry about your speed or performance. I'm as slow as hell and manage successful projects, very hands-on. Find your niche, and don't expect to be good at everything.
