By doing it part time, you minimize your risk both in time and finance as your still have a full time income. (in fact, that is how I started my computer career from home).As you still are earning a full time monthly income, it will give you the confidence and money to invest in your part time career. You don't have to worry about the payments of your monthly bills and can focus better in developing your part time career until it can earn you a SECOND source of full time income.
There is always a learning curve we need to experience. Your first attempt of starting a part time career could end up in failure for various reasons despite your enthusiasm and determination to succeed. In such an event, at least you could still fall back on your full time income.
With your full time career as a backup, you are not under tremendous pressure to perform in order to survive. You still can live normally as you developed new skills, knowledge and you can grow your second source of income at your own pace.
You continue to enjoy the benefits of a full time career such as health insurance, annual leaves, bonus and other benefits that your company may have given you as an employee while you develop your part time career into a full time income.
