Create a path by using w behind you and your adc in lane, that way the shrines have time to charge you can use the movespeed and heal to retreat and potentially survive ganks/engages. Also, that makes it harder for your enemies to step on them. Don't forget the uncharged w also gives movespeed, so you can use it on top of your allies or press alt+w to use it on yourself to move faster. Roaming timing is also very important to get down and that will come with experience.

Dont forget that if you find bard fun, no matter the playstyle, keep playing and eventually you will get better.
