This is what I can do
Maybe you are used to saying this sentence. You can’t do more because you don’t know how. Really? Have you tried learning more things and applying them? Have you put all your efforts in the outcome? Have you tried to think different and approach the problem from another perspective? Have others helped you? Many people are sometimes lazy to go deeper and improve themselves. Others persist and after some time, the results pay off. You choose. But never leave a project saying that you can’t do more. You can always do better. And you will do so if it’s your will.
