Passion and Practice
To become professionally skilled at something they reckon you need to work up 10,000 hours practising the activity. For most people dedicating that much time to anything seems daunting but I think the key to clocking up that much experience lies in being passionate about it (Duh).
If you are working at/practising something, and have a deep love for the activity, then the activity doesn’t seem like work. Hours literally pass while you are having a good time, so someone who enjoys carpentry and can spend 8 hours a day in their workshop without thinking about it will easily reach the 10,000 hour benchmark. However someone who unhappily works at something, rarely spending half an hour a day, will never develop to the same level. The unfortunate thing about this is that once a certain level of skill is reached then enjoyment comes simply by being good at the activity.
Once an expert level of skill has been achieved the return on the hours dedicated starts to plateau, it requires many hours a day practice to maintain proficiency.
If at any stage the passion disappears, the willingness to simply maintain proficiency drops and there will be a decline in skill. The negative feedback loop occurs here and because of the loss of skill there will be lower levels of enjoyment. Meaning that further decline in skill is imminent.
This is why passion is so important for anything, passion makes developing a skill easy, but also means maintaining the high level of skill is possible.
Always Follow Your Passion, it will guide you to the best place to be.. the top percentile.
