The popular saying goes: "Jack of all trades, master of none", and refers to someone with relatively superficial knowledge in various fields, while not being outstanding in any particular one. Dabblers, dabbling in different fields, accurately fit this description.
Now, as one seeks to improve himself, he can look for information from various places. Some sources say, to become an interesting and more complete person, we must try many many dishes from the feast of life. We must 'try' everything, so that we know about alot of things.
Others, such as 'Mastery' by George Leonard, talk about the way of mastery, telling the reader that the route to mastery is the ultimate pleasure in life. Mastery, the conscious and continuos practice of one field in which the person find peace and pleasure.
At first glance, these may seem the contradict each other. However, it is rather logical to conclude that, in order to get on the path to mastery, we must love the field. In order to know whether we love it or not, we must dabble in a few. They will all invoke one emotion or another, but when we find one which we enjoy doing, and not just enjoy because of the end results, that is the one we must get on the path of mastery with. And it is to find this specific field, or discipline that we initially dabble. And as learning is a lifelong process, we continue dabbling to find more things to master. A woman (who's name escapes me at the moment) on her 70th birthday decided to 'dabble' in mountain climbing. She has since climbed many of the major peaks around the world, at 95 becoming the oldest person to climb Mt Fuji.
In conclusion, dabble, but use the dabbling as a way of gathering information, not only of the world, but of your initial responses, and use them to choose specific fields to master.
Become a Jack of all trades, and a master of a few.
PS: Read Mastery by George Leonard. It will make alot of little things in this passage clearer.
