Whether it's in academia or in the professional world, people often ask themselves "Can I do this?" As a student, this question is often running rampant throughout my brain, ricocheting with due dates and assignments. Some tasks may seem daunting at first, but you are far smarter and more capable than you give yourself credit for. It may take a lot of effort and hope, but you can do it.
The fact that you're asking yourself "Can I do this?" is a good sign. Many would think the opposite, because if you're second guessing yourself, chances are you've never done this before and don't know if you can. But I say: The fact you have momentary doubt means you're on the brink of learning a new skill, developing a fresh talent, and discovering how intelligent you already are in that discipline.
In this "day and age" we are fortunate enough to have a plethora of resources, like the internet. When you don't know how to do something you can just type the problem into Google and get millions of hits with ways to reconcile the situation. It does not matter how many times you have felt inferior with peers or colleagues in the workplace; the world wide web is an incredible tool to turn to. But you can do it.
I turn to the internet to learn simple things quite often, like changing the clock in my car.
You are as intelligent as you believe yourself to be. I am a strong believer in self-empowerment. If you have confidence, anything is possible if you're willing to work for it. Effort is required for anything of substance. Whether it's a relationship, assignment, or job position, exertion is necessary. But you can do it.
Martin Luther King Jr once said, "We must accept finite disappointment, but never lose infinite hope." Disappointment will be present in your life, no matter what you pursue, but if you do not have hope, you lack the drive and even possibility of achieving your goal. But you can do it.
With your wit, work ethic, and willingness to be optimistic: You can do it.
"In order to succeed, we must first believe that we can." -Nikos Kazantzakis
You can do it.
