It does not matter how slowly you go as long as you do not stop.
It can be tempting to measure yourself against others, especially when it seems like they are achieving things before you. It doesn’t matter how fast you get something, what matters is that you get it. If someone you know can write a paper in a day, and it takes you three…who cares? Just because they are faster doesn’t mean their product is better than yours.
People learn at different rates and in different ways. Whether you learn something right out of the gate matters less than whether you take the time to learn at all. Study, practice, ask questions, seek guidance, keep going in pursuit of knowledge and you will get there. Whether you are trying to learn a skill (like paper writing) or acquire new information, through perseverance you will achieve your goal.
