Focus. Focus can be a very important thing in life. Generally speaking, focus is needed for almost every aspect of life. If you don't focus, you don't succeed. In some cases, if you don't focus, you don't survive. But focus is a double edged sword. If you focus on something too much, you are probably going to exclude other things in your life. For example, if you focus on work too much, it is likely that family life will suffer. If you focus on gaming too much, work will suffer. If you focus on any one aspect of life to excess, all the other areas will suffer. It could be compared to using a magnifying glass to focus the sun's rays into a fine bead. It's great if you want to start a fire, but if you look at that bead too long, everything else fades into the background. In other words, strive for balance.
