Setting yourself up for Success

For those of you who have made a career transition into CSM from another field/industry, what did you do to make sure you set yourself up for success? I have joined this community to learn and grow, have established relationships with a couple of CSMs who I look to as mentors AND I am currently reading The Customer Success Professional's Handbook?  Any other advice that you can give will be much welcomed. I start my new role on Monday and wan to make sure I am doing everything possible to succeed in my new journey!

Thanks in advance!
