As someone who only passed their driving test about 2 months ago, I understand that becoming a new driver can be difficult and I don't think that people talk about it enough. Once you pass your driving test everyone just assumes you'll be fine with driving wherever whenever, but this isn't always the case.
Being a new driver, it is normal to want to take it slow at first, or at least the speed limit, but one thing they don't tell us is that most of the time, the car behind us often wants us to speed up. Never feel pressure from another car to go faster. Always go at your own speed (however always try to go at the speed limit). Make sure you feel comfortable first and then everything else will come naturally.
Don't Be Hard On Yourself
Comparing yourself to others is the main cause of being hard on yourself when it comes to driving. Everyone learns at different stages and there is no point in judging yourself based on what someone else is doing. It doesn't matter if you pass your driving test a year after everyone else, it just means that they had that year to practise and you have the next.
Understand Your Car
Chances are, your car is going to be much different from your driving instructor's car, (unless you use your own in lessons) so learning about how your car works is important in making you a more confident driver. Learn the biting point and how the brakes feel by going out on easy drives at the beginning to make you feel more comfortable before you set off on more complicated journeys.
There is absolutely no shame in keeping someone with you in the car while your driving until you feel comfortable enough to do it on your own. No one expects you to be a Formula 1 driver a week after passing your test, so if keeping an experienced driver next to you for a while is going to help in the future, never be embarrassed about it. Have someone you trust next to you, so if you do stall then you know they won't care.
It isn't often you have driving lessons at night (unless you have a lesson in the winter at like 4pm!) so it can seem daunting to then be thrown in the deep end and drive at 10 o'clock at night. However, driving at night is just the same as driving in the day, just with headlights. My advice for this would be to just go for it because you will be surprised at how easy it is.
