Never, and that doesn't look like something that would benefit anyone neither, it doesn't really feel like it would be wise decision neither, it should not be a big deal and it should not be all that much more important than people think it is. We need to realize that it is going to end up with something that should not be all that much of a big deal, and journaling could be done a lot easier than this.
We need to end up with a good return that could potentially cause everyone to have much greater risk and should not be all that simple. I get that it is going to take a while, but it needs to get to a point where it will not lead to a greater risk neither, when you are dealing with foreign programs you never used, it's added risk, and the reward is not worth it.
Maybe for you yes but there might be people who think it is very useful. Even me, I think it was, because it allows us to see our performance and we will be aware if what areas needs improvement. BTW, have you tried doing it before, for you to say that it's not beneficial? Maybe you did something wrong, though you can always try again. But before that, you can also look how others did it successfully.
You can get an idea from them. All of us wants a great return on their trades but it's just that it won't easily happen. The risk is also big. Maybe when we master things, the risk will also lessen, but I'm sure we will find a way to elevate it again, in hopes of earning more profits. That's us people, we can't easily have a contentment.
