After getting my Bachelors I started working full time and was considering getting my Masters. Since I was used to the fast pace busy life of college and my job at the time was only 40 hours a week I started taking classes. I soon decided to work full time and finish my Masters. The rest is history!
I recommend that if you want to complete your Masters you do it soon after completing your undergrad and have a time frame in mind to work towards to complete your degree.
