In life you will face ups and down. there will be so many obstacle that will kill your hope. but remember it is you who can solve this.
In my life it was not so easy for me. Doing full time work along side with study is pretty much haptic for me. Sometimes I couldn't get well prepared for my class. Sometime I get so tried of this , but instantly I got motivated by my hard work. Then I think all of my family members , my father, all of my relative who are really counting on me. So, every time I motivate myself by saying, "I can do this. It is me, who can lead".
Remember one thing, ALLAH (GOD) will show you the path, but it is you who's gonna earn that by your hard work. So many people will criticize you for doing a good work, they will make you false, they will judge you wrong but it is you who's gonna break all the barrier and be the one what you want to be.
Keep yourself motivated, what everyone want give them your best. Work hard, stay positive.
