Seeking knowledge at old age is like writing on water. While seeking knowledge at young age is like engraving on a stone. It lasts longer.
Young mind is like a sponge. It absorbs almost everything. Everything we read, we learn and we practice will be planted in our minds like seeds. So, be careful in choosing what we plant in our heads.
To young people out there (i'm no longer young, i think), make full use of your youth. You have energy, you have time, and you have all the recources in the world. Quit wasting your time doing useless stuffs that you might regret someday.
Read a lot. Equip yourselves with as many useful skills as you can, coz we don't know which one might come in handy later on in life.
And just because, you can!
