One thing that all pilots should learn early in a flying career is to protect your logbook at all times. That means not leaving a logbook at the flight school after you get your PPL. That book is more valuable than the family bible. The bible one can replace but once a logbook is gone it is gone.
Never leave it at a flight school unnecessarily, never leave it in your flight bag in your car (in case the bag gets stolen), keep it spotlessly neat and tidy, keep it up to date, do not write up ghost flights (false entries), use a standard or slim size logbook, the big thick ones get tatty over many years,
Use more than one line to write up a flight if need be. A log book is cheap to buy so why try and save space writing up the details of a flight.
Keep a logbook that others including your kids can read and understand in 20 years time and the next employer can read at the interview. Go easy on the abbreviations.
To not see a logbook left at a flight school 12 years ago means you have more chance of winning the lotto.
