THE most important lessons in life is that NO ONE ELSE can make you successful. It's all up to you. YOU are the "master of your destiny" and responsible for your own success. Period.
Conversely, there's not anyone or anything that will make you a failure. It does no good to blame the economy of Nigeria, your education, or whatever bad breaks you've had in your life. Doing so means taking on a victim's mentality. DON'T EVER DO THIS. I can guarantee you that many thousands of people have succeeded despite having it much worse, so don't make excuses and don't convince yourself that you're somehow a victim.
And the grass isn't any greener on the other side either. You have now (or can acquire) everything you need to be successful. Just remember that it's up to you and nobody else. Then go out and do it.
I have grown to strongly believe that If you want to become successful, you can go around the obstacles, go over, go under, or go right through them. Success is yours if you want it, but ONLY YOU control this. Always remember: "If it's to be, it's up to me."
Here's some more quotes for your reading pleasure;
"I don't know what my future holds, but I do know who holds my future."
"I found it easier to get rich than I did to make excuses."
"He that is good at making excuses is seldom good for anything else."
"I used to say, 'things cost too much.' Then my teacher straightened me out on that by saying, 'The problem isn't that things cost too much. The problems is that you can't afford it.' That's when I finally understood that the problem wasn't it-–the problem was me!"
"Don't wait for someone else to make your life terrific. That's your job."
