Please correct my mistakes If possible. Do you prefer to spend your time alone or with friends?

Personally I prefer to spent spend most of my time alone because I can be free for studying and working and I can focus on my plan more and more. But you can see when I am alone I am talking or relating with people due to that my major is dependent on. So most of the time I am not alone! I believe that when I am alone I can learn more but I nice know that some friends are so helpful and when I spend my time with them I am happy more more happier and I can learn new things from them too! I think preferring spending time alone or with friends is got back our personality and plan inside of situation or opportunity! I prefer to be free for choosing any things so I can enjoy both of them. Please correct my mistakes. I will be so grateful.
