New A&P at regional airline seeks tips to sign off maintenance confidently

[LarryJR]

I'm a newly licensed A&P mechanic starting my first job at a regional airline, and while my training was thorough, the sheer volume and pace of scheduled aircraft maintenance in a real-world hangar is overwhelming. I'm currently shadowing on routine checks, but I'm anxious about the responsibility of signing off on my own work soon, especially for complex systems like hydraulics or flight controls where a mistake could have serious consequences. For experienced mechanics, what practical advice do you have for a new tech to build confidence and ensure meticulous accuracy in this environment? How do you manage the pressure of tight turnaround times while double-checking every step, and what resources or mentorship strategies were most valuable for you when transitioning from school to the line?
