A common problem of programmers is, that they want a solution they 
already know for a problem they already know, even if it is the worst 
solution the can choose.

There are so many possibilities to solve a given problem and you even 
have time to do this before your application get released.

Also: if you rely so heavily on hints, then use a database which 
supports hints. A basic mantra in every training i have given is: use 
the tool/technic/persons which fits best for the needs of the project. 
There are many databases out there - choose for every project the one, 
which fits best!
