I keep a spreadsheet of every fishing journey I take. The spreadsheet gives the date, the time I go, where I go, the conditions (like weather conditions), a brief write-up of what happened (ie. Gear used, lures, peculiar experiences), the number of fish I caught and a cumulative total. It really helps me down the road to see how well I've done in a certain place and at a certain time using whatever gear I used. It's been very beneficial for me! I've done it for about 3 years now.
