I'm sure you've heard the term "licensed to learn". No one expects a fresh A&P to step in and be self sufficient right off the bat. You become competent over time, but you "never" stop learning
Things like daily check items, tires, brakes, and fluid servicing come pretty quick. Others like component replacements, rigging, and troubleshooting are not required on a daily basis, so skill sets take longer to obtain.
Most major airlines have some sort of apprenticeship programs. Maybe some FBO's also. If you end up working corporate or piston-poppers, you'll probably find experienced mechanics who will be more than happy to teach you.
It's in everyone's best interest to pass along knowledge to the next generation coming in.
I was a "young buck" once. The old farts taught me.
Guess what???? I'm the old fart now. This site was built to pass along whatever I have learned to others.
