Abother thing to keep in mind with investing is using the average price over a period (not sure that it is correct wording in english, so correct me here, if it is wrong).
That way you spread out the eisk over time and usually make more money in the end. It also helps develop patience, and perchance for instant gratification, that are your enemy in trading, especially if it is speculative.

Anyhow, people if you found my comment insifghtful do check out my post about the beauty of Buryatia, which I did during hitchhike to the nearest bit of civilization. Part of the #payitforward thingy. :-) (and here is more or less how to do it correctly).
