THE FUN IS ALWAYS IN THE END

It's ok if you feel bad now, it's ok if nothing good is happening now. It's ok if you are sacrificing a lot now, the fun is always in the end. 

Work hard now, do your best, learn to endure because you will have a lot of fun in the end when you become successful. 

Let them party while you are working, while they are eating you are grinding. It is what it is, you have to make sacrifices or else there will be no rewards in the end. The fun is always in the end. You can't be having fun in the beginning and expect to have fun again in the end. If you have fun in the beginning then you will get misery in the end, as simple as that. 

Endure the hardship now, have fun with the challenges because the bigger the challenge... the bigger the success will be.
