The guide is very well-written and complete in itself which will make an excellent guide for newbies who are trying to gamble! Nothing is better than sharing your own experience to something since you know what it feels to be in their position before.
On a side note, if newbies are trying to gamble with the view of making it as an avenue of earning income, then it would be best to avoid gambling. People who gamble for entertainment are more likely to win than people who gamble for making it as source of income. The problem lies with the latter being stuck on a vicious cycle wherein regardless of the result, he/she will still continue.
Again, most will mention about self-discipline and control but these are all true. Oh one more tip, do not ever bring your card and just bring some limited cash!
