The mistakes I do & repeat it even if I know :)

I am a human :) (wow at last I think I am a human) in my job I do one big mistake, which I know about, I may be doing even more mistakes but I need to hunt them down someday.
So about this mistake, I don't know what technical word is given to this habit, its like this say I am working on a problem (off-course its about my job) and as usual I don't know anything about it, I try to hunt it down as soon as possible but when I am stuck the usual thing normal people do is take help from a person who already knows about it but me me....I don't do this but instead I hunt around and this goes like a circle, few problems yeah I do get solutions, its not gr8 because already ppl know about this and me just discovered, but my inner feeling is like "wow I did some thing gr8" this feeling is a evil in disguises to me as for other problems I hunt and I can't get the solution on time but to get this gr8 feeling I try and try but at the end it like, the problem which can be solved by a person how knows things better can do it in say some 16hour I spent the whole week :( ie 8hours * 5 (40 hours) but still I am now where.......
This is my biggest mistake, I do all over then I release but then latter when I am into problems I forget or negelate my mistake and I am allover again doing the same old mistake :)
The other mistake I do is like, when I am looking for solution for problem 'A' I hunt it down, but during this period if I see other things like 'B', 'C'.....I get involved in tooking into it for getting knowledge about them and I just get deviated from problem 'A'.
I need to over come this things, hope I do and soon as I am getting nearer to 4years of work exp I need to be more smart and more control on my self taking in to account of any problem (technically).
