Anybody else have the problem of find a satisfying martial art?

I think I understand what you mean. I've had similar debates myself when I was younger. So here's my two cents worth. The terms "fun and enjoyable" are pretty subjective and may vary from one person to another. What may be fun to you may not be fun for me. So making it a major part of your criteria is probably one of the problem. Self defense in itself is a good enough criteria to take up MA, but you must remember that having to defend yourself in a real life and death situation is no fun and therefore should not be taken lightly. So if you find no fun in doing heavy exercises and repetitive drills that take a lot out of you or don't like going up against bigger or stronger sparring partners who show a lot of ruthless aggression than you are comfortable with, just keep in mind that these are probably the same situations and the same type of people you might run into in a real self defense situation. We can't always choose and pick the cirstances of having to defend ourselves and our attackers won't give us a five minute water break just because we're thirsty or ease up on us because we have a hard time catching our breath, we need to train ourselves in having to defend against an aggressive attack while we are exhausted and scared as heck, so that it won't be as big a deal when it does happen for real. In the end, you might have to choose between practical self defense or fun and enjoyment. From my experience, once you get to be good at something, that's when the fun starts and you begin to enjoy yourself. You just need to hang in there for the long term instead of skipping from one place to another in search of the magic pill, there isn't one, fact is, there is no substitute for hard work and commitment. Doesn't matter what art you study. Took me some time to figure it out, but I finally did. It's all up to you. Your life, your choice, your call.
