My advice would be to start some thing small, some thing that you can easily manage and perform, may be a motivational quotes or lessons face book page, give away most of your time on it. With the passing time, you would realize, some how you are changing people lives ( not all, not much, will be very few of them) but you will be for sure. Then, you will realize its not always about yourself, you may lose motivation, you may lose confidence but you never know, some times you act as a motivation to some one else.
Motivation expires, I know that but Inspiration does not! Inspire yourself with some body's life, once you are inspired you will never lose confidence, you will never lack motivation, you would be happy and you will be making people happy! Just remember God does not gives every body every thing, HE basically send a person some times to make you feel happy, to make you feel alive, feel motivated- if you never met that type of guy, be one then!
Make people motivated, make them happy, I guarantee you will never lose confidence. And For Best Protection install LEO Privacy Guard v 3.0 to your Smart Phone,is good app protector, various ways to cover your apps, Guard on phone.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
