What is your nature of bug fixing?

Answer 1

Fix one small issue, then give up when 5 more errors appear. Then I ask for help, fix those 5 errors, run it again confident it would work, then actually smack my face into a table when 10 errors appear. I then give up and wait 2 weeks until I try again. The cycle repeats.

Answer 2

Get yourself a list of everything thats wrong or missing. Then start with whatever you like (or what other things might be based on) and start trying around till that bit works, cross it out and go on to the next problem.
