I do budget but I'm not a freak. I just use an excel to keep record of my expenses so I can plan properly. When I started budgeting I kept record of all my expenses but now I know more or less what I spend. I only revise and write down expenses on certain categories if my spending habits change or when I believe prices have gone up more than 10% in that category, as I always budget a 10% extra of what I usually spend.

You say you are budgeting because your personal finance is not that good but you would be surprised about how many people keep budgeting even after year of being in a comfortable position.
