Will power is really beneficial according to the society today, but I would like to discuss some of tis disadvantages today.
Hopefully you wind it inspiring or entertaining :)
If one only use will power for doing things one will naturally be drained or burned out because there is a time in every persons life where will power on its own dosen't work anymory, you can only push yourself until a certain limit.
This happened to me when I was studying at University, I had pushed myself towards my limit and when I reach the limit I couldn't push myself anymore and the only option was to quit my studies.
Then I had to figure out other ways to live than to push myself all the time and began to think what I really wanted to do in life.
So if you are pushing yourself everyday then that is not good, because there will be a time when you can't push yourself anymore and if you don't know what to do then you will be very sad and depressed because all your energy is gone. I speak about mental energy now, which is the cause of depression if it is very low and you can't enjoy things anymore.
Then you need to learn how to relax and let things be so you can build up your mental energy again.
And another thing is that to use will power to get through the day is not a good idea if you want to be a happier person, then your will power will counteract with your mental energy and happiness along the way.
So will power have its disadvantages it is the main conclusion I will discuss today, and remember that you can't always push yourself on doing things because then you will be burned out and feel very depressed afterwards.
