...and with consistency, and persistence, i multiplied my effort and i now earn something higher than that.
Sounds weird but it actually helps improve (one's) capabilities even with my acadamics . When you STAY consistent for quite number of time, you build upon your values. Even though you wouldn't be catapulted in a skyrocketing manner, you will never be the same you were days or months before.
That's it. Everyone progresses with different momentum. All that it takes is time if you are doing everything right in order to succeed.
