a question on programming

[konny]

This is off topic and I aplogoies in advance if anyone is offended.
If it TRUELY offends tell me off list and (better still) direct me to 
the appropriate listing. Please do not waste the thread ranting and 
counter ranting..

I am not that new to programming but consider myself an old novice.  The 
problem is I find myself often with a difficult dilema when coding.
How do you prioritize your coding responsiblity between:

functionally
 Does it do what its suposed to do, can it do more, has it been future 
proofed [what's that ;)]

speed
It's the code efficient

validity
can it handle all possible data

security

Another factor:

I know their are methodologies that cover the stages,and I know it can 
depend on the application / service being provided but what I'm asking 
is when YOU are coding which do you consider first ..   last and why. 
 Have you every considered this or am I just wasting characters?
