Success is not for everyone. It comes from thorough self-management and hard work.
Time goes.
The saliva you shed now becomes the tears you shed tomorrow.
Study like a dog and play like a sage. (I've seen it a lot.)
If you do not walk today, you must run tomorrow.
Those who invest in the future are those who are faithful to reality.
Education is money.
A day spent today will not come back tomorrow.
Even at this moment, the bookshelves of the enemies are falling.
There is no gain without pain.
