What is flexible enough?
There are a few different options you can do, so that you can enjoy your surfing time. One of them is finding a job working from home. Working from home can cut down all your commuting costs, which if you think about it, can save you a great deal of money. Another option is getting a job in the legal field. Legal jobs can be part time, and all you need is your paralegal certification.
Is this going to be enough money?
That is up to you. Most is pending on what your bills and expenses are. Get yourself on a budget, and spending wisely. Another smart thing to do is start a savings account.
Enjoy your surf time.
