I might be a bit ahead of the pack here - broken ankles a long time ago as a teenager and repeated issues with them growing up so having to leave most of the harder impact tricks behind and had a lot more time to skate ramps, in particular smaller half pipes, which only got a lot more intense the last decade of having a mini ramp of my own to skate and all the rest of it but there are some very interesting points to make about learning transition tricks on anything, not just on quarter pipes or half pipes, mini ramps or the like.
Regardless of what you can or can not do on coping, there are many things you can learn well below coping or at least on mellow bank edges or almost anything else that has some sort of lip. For a normal ramp, have an imaginary line somewhere on the face and do things like frontside and backside fiftys or five ohs and work them up higher and higher, gaining confidence and skill. Same with other things like front or back rock n rolls, fifty reverts and many other things. The top of a mellow bank is good to take things to that you need an actual lip but are not as confident to do on coping as well, including things like blunt roll outs or pivot to fakie, where you can sit on the top and turn it back to pivot to rock to fakie easily without fear of hanging up. If that is a little too far ahead, think of it as a future investment in tricks to learn on the most simple and basic of things, to then take up higher and higher or to where ever you are comfortable.
The best example for learning basics is things like fakie tail taps, which can lead into and are almost the same as fakie tail stalls, but you can do them well below coping and you roll up with minimal speed and just tap the tail on the ramp at the moment you are about to stop, where ever that is on the ramp, keeping your weight over the front foot so you cannot slip out. Work these up higher and higher, staying low until you are at the point where you can just tap the coping, which then gives you better balance to be able to pump a bit more and really put that tail down to stop and then drop back in.
Other tricks that you can do on a curb or even a driveway bank can also be converted to mini ramp easily enough, but having a suitable ramp or even decent quarter is the best place to start, just to get comfortable. In the event of a quarter, start closer and closer to the face, so you do have to make sure you get your feet in the right place and be ready to hit it with basics or tricks you know and can do, which will make it easier to get used to thinking quickly and doing things back to back on each wall.
Lastly my go to for inspiration is setting up a camera and watching back some of the things I have done - just having a camera out makes me push myself more than if or when I am just rolling around by myself, but also watching it back I can see what I was doing and if there was anything I needed to be doing differently, which for the most part is getting down lower and turning my upper body more to get into some things, especially frontside as I tend to get very lazy and jump off or just let the board go on a lot of tricks I used to be able to do a lot better when I was younger.
I post a fair bit on Instagram (occasionally some of it on Slap too) but really it is more just for me to watch back, or for people who might want help learning tricks, so I will film a trick or something in a line and post it, then send it to them, often putting up the other random things I have done too.
These are the two main tags for this sort of stuff, which I think is probably better than posting actual clips here, the rampjam one is some humour from my love of Jims Ramp Jam video (which was an amazing old video to watch) and the second one is more just everything else, some overlapping, mainly older pics and newer videos too.
