“If I have seen further,” Isaac Newton wrote in a 1675 letter to fellow scientist Robert Hooke, “it is by standing on the shoulders of giants.”
Look at society around you. Look at the technology, innovation, quality of life, fairness, etc. Yes, there’s more to do but we live in such an extraordinary time and place.
As a society, we have gotten here thanks to people throughout history just like you. They have put in the hard work and endured the struggles to build what we have today. You can carry this forward in your own way and contribute to building society even further. You will undoubtedly have your own struggles and challenges. When you are pushing boundries and stretching it will usually be very difficult. But realize the exciting future you are building for yourself and future generations.
