Best advice that I have had was do not rush in to buying the most expensive and latest product around.
The other piece of advice is 'take your time'. Do not be in a rush to shave. We are all used to doing things against the clock, in a hurry. Shaving is something to be done at your own pace and for your own pleasure, do not try and do sometthing in one minute that can take 10.
If I could offer a single piece of advice, always moisturize, whatever your age, it doesnt have to be a big bucks big name brand, you can get something sorted which will cost around £3/$4 for 100 ml and your skin will thank you for it, in 10 years if not now.
