There is a lot of stuff going on in the world which i would write about but for the problem of lashon hara [slander]. And this is a delicate issue because of the severity of the issue. I might be required to warn someone about hanging out with the wrong sorts of friends, but if my words are not accepted --,is that lashon hara?
And the whole issue tend to be forgotten on the larger scale. So I try to mention only the positive things that I and others ought to concentrate on--learning Torah "beiyun" in depth with lots of review. Going through the Gemara with Tosphot, Maharsha, Hidushei Reb Chaimof Brisk, Mathematics Physics, exercise, coming to Israel etc.
i mean to say, if you are careful about Lahon Hara, what else is there to do but to learn Torah?
