I would suggest you to start work before further studies however preferably in your area of studies if that is you are still interested in.

The more working experience you get, the higher your chances are of progressing in your career early. Also work experience will help you with studies since you will be able to apply your knowledge at work. Studies will improve your performance at work. It is a win- win situation. Still I would advise you not to postpone your further studies too much. If you can, have your classes in evenings or part time. It is not too easy but it is not too hard either. You just have to take the first step and you will reap your awards sooner than anyone else at your age. Carpe Diem!

I suggest you to continue both study and work together

Go to work now. There's no point on continuing to study now that you have a degree to fulfill your needs. The only reason that you would continue to study is so that you'll have a higher wage, which is a selfish reason. Another probable reason is simply the thirst for knowledge, which would benefit no one else but you which again, is selfish. Instead of going to higher studies, why not devote your time instead to a charitable organization, or better yet, join the ministry to preach the word of God, the one thing which we can all say is worth doing which benefits us all. Just be careful not to preach the false doctrines though.

Having a degree is very important and will help you alot in the future. It is best if you can do both, but if you feel the need to work to be able to save up to continue your studies then go and work first, but when you start working and stat loving it, you'll loose interest in continuing your studies. This happens but not most of the time. Assess yourself and weigh your options.
