For the newcomers or those that may want to become Part 107 licensed in the USA:
While studying for my Part 107, the instructor in a $50 class said the following:
"Now here is where you are going to kick yourself. Remember when you got your first drone and started flying? Log ALL the flight times. It does not matter if it is hobbyist flight time or commercial flight time...it is all flight time. Say you walk into a commercial job and you mention 'I have 20 hours flight time'. The customer will be like 'that's nice'. But show you have 200 hours and it will be 'let's do business'."
