I am not really quitting; In fact, I'm nuts about bonsai!
But... Sometimes it's frustrating when some well cared for trees die and one has no clue as to why it did happen...
While the masters here chop, saw, defoliate, bareroot and their trees ROCK!
I hear ya Clicio.
I'm not certain what your age is, but I'm will be 59 on 2/20/18, and after being away from Bonsai for a very long time, I decided to re-enter the hobby.
Reason being is I'm planning for retirement within the next couple of years or so, so I want to have all of my hobbies fully tooled and in full-swing (Bonasi, Cars, Heck I even started to learn how to play the Banjo, which I've always wanted to learn! LOL...).
Anyway, as I peruse BonsaiNut as well as a few other highly informative Bonsai places, I keep getting even MORE enthused and involved.
The people here are fantastic and they are always willing to assist, no matter what stage of the hobby you are at.
Sure, it can be overwhelming at times, but hey, it's STILL a blast to learn different methods/approaches/ideas and create living beauty.
I know this will sound cliché, but do keep your chin up & stay focused.
I hope you're enjoying the Bonsai ride, as much as I am!
