Farmers understand that the underlying principle standing between seed-time and harvest-time, is growth time. However, concerted the seed-time may be, nothing will be harvested if growth did not happen.

In that vein, farmers will ensure their seed(s) are watered, exposed to sunlight, protected from weeds etc, in the hope that at the harvest time, there will be multiplication because of growth.
 
In career development, I have learnt, TRAININGS are your water, sunlight and air. You won’t get very far without them. Any tool or organization that brings training(s) your way, is interested in your growth. And mind you, no one will better seek your growth than you.

So, take charge of your learning!
