Forget about who others think you should be and become the person you want to be. If we spend all our lives trying to please others, trying to fit into the mold other people think we should fit and working to be someone we are not, we will never be able to reach the goals we think are important. We all have the capacity to do amazing work, but we have to embrace our own uniqueness and do what moves us.
We all have others we look up to and want to be like, but we will never be able to do the work they are doing. We have different passions and desires and thoughts and muses and will only be able to be the person we are. We can have mentors and heroes, but we are all different. We do things our own way and think in our own terms and dream in our own way. We will be able to do so much more when we embrace who we are, when we become comfortable with who we are and when we choose to use the talents we have to create good.
Be the best you possible. Don't try to be just like anyone else. Embrace your quirks. Figure out how to use your talents to do the things you want to do. We will never be able to do what we want until we become comfortable with who we are. This sounds very easy, but most people will tell you it is not. We all have doubts. We all have faults. We have to become adept at not listening to the doubt and acknowledging and improving the faults. No one has lived the same life, had the same experiences or have the same mix of passions. Utilize what makes you different to bring great works into the world.
