I've played with bonsais for about 15 years. Lost most of them when i lived in an upstairs flat though about 10 years ago. Still have 1 original though.
I like how many the things you do in bonsai are so arboriculturally incorrect
Like ripping big wounds down the side of a trunk to initiate decay to age the look of the tree, make it look like its been struck by lightening!
Of course, being an arborist i cant bring myself to do alot of those sort of things.
I tend to do minimal invasive stuff to em.
