Regarding the luck factor of knowledge, you must possess distinct benefit. The great majority of people drift along and generally not informed that their knowledge is restricted and that whatever knowledge they possess is becoming obsolete with each passing day. Many of them spend their time socializing at work and at home, many spend their own on irrelevant things like watching TV and generally living as easy a life as possible.
However, the Small but the enlightened minority, like yourself who actualize or realize that we're into race for practical or useful knowledge, have the winning abilities edge of them. You're already ahead of the pack due to you are aware of what you need to do to forge ahead or to move to the peak of your profession.
Thanks.
