Problems in the process of Linux learning __linux

I have some time to learn Linux, because I learn Linux is entirely out of their own hobbies, there is no evaluation method, how to learn how to rely on their own feelings. The process of learning is also entirely with their own ideas, precisely because of this, so that the process of their own learning in the methodological aspects of some problems, can only rely on the feeling. So put them out to warn themselves, hope can be corrected, not again.

1, too blind, no purpose, at the beginning of the time just casually learn some things, see online there are posts to say what, feel fun, and then do their own play, it is in the process of playing, wasted a lot of time, but the things learned are very limited. Although this also expanded their horizons in various areas, increased interest in Linux, in the introductory phase do not know what to do with Linux, and the loss of their own is a certain help, but this process is very easy to follow the consequences of the end. Slowly to have some preliminary understanding of Linux can be completely abandoned this, for example, if you are interested in Linux as a server, focus on the Linux system Management knowledge, if interested in its core, then in-depth study of his kernel mechanism, so have a clear goal, It must be more efficient to learn.

2, just a simple imitation, thinking too little. At first just because I do not know where to start and casually find some posts to see. Later encountered problems are always to be found on the Internet, but the online method is not necessarily effective. So most of the time just holding a try on the mentality, but also according to the post to do, and not to think too much, the final problem can be solved, it is just luck, the problem solved their own do not understand why, the next encounter or the same need to find online. In this respect, at first I think it is due to limited capacity, do not understand, resulting in memory. But slowly when they know something more than a little later, or appear such a situation is entirely because of their laziness, do not want to think, also do not want to remember.

3, in reading and learning, too much of a cursory, a lot of time is just the pursuit of speed. And forget the due understanding, and finally read a no gain at the time also have, there is sometimes understand but lazy in practice, and ultimately do not know whether they understand the correct or not.

4, the last one of the most serious problem is, too much pursuit of some flashy things, such as setting up some 3D desktop, modify the boot start of the theme, and so on. These things know on it, do not have to be too engrossed in this, do not understand its principles, casually get a set of not too much use. It's also easy to bring problems like this to the system. For example, once installed 3D desktop, inexplicably no icon, the system is therefore unable to use, because do not know how to solve, you can only reload the system. There is also a compilation of the kernel can not start after the original compilation of the kernel has a problem is very normal, but that time. After installing your own compiled kernel, not only does your own kernel have problems, but also the previous kernel has problems. And do not know how to solve, you can only reload. I don't know why, but I think it's probably about the grub that was previously installed.

Record your own reflection as an incentive.
