Room in Mind

Recently, I think that I need to love myself first before having a girlfriend, because you cannot make people happy unless you are happy.
In order to love myself, I need to make more money because I don’t have any room in mind to think about others with my limited salary.
I feel that the salary of teachers is not that high, but they feel much pressure from the parents, Board of Education, and the principal.
It is not allowed for teachers in public schools to have a side job without permission from the principal.
I will prepare for the next school year to do a new job such as programming.
