When I first got interested in card magic I was looking for some false shuffles and somehow I found a video he built the deck into about 6 packets one of his chin and starting twisting the packets, I had no idea what he was doing it went for about a minute, he closed the packet and spread the deck out everything was 100% in order and I was amazed, by then I had been doing card magic for about a month and learnt a simple 3 packet false and used it in routines after that I learnt another 3 packet which was harder and from than you just find cool video's.
I got hooked, flourishing is fun.
I found when I learnt a magic trick I liked it.
But the accomplishment of learning a flourish is great, for example a sybil, you start practicing the sybil for hours, until you have it perfect.
The result when you see the sybil in the mirror the feeling is so great, I never had that with card magic.
I purchased kevin ho's book and learnt Punk'd which made me feel really excited about that, other than that flourishing always make me smile when i learn a new one.
