Read the newspaper regularly
Every literate person should adopt the habit of reading the newspaper regularly. If you go through the news on day to day basis, you will definitely find something new to write about every day. News circulation is so efficient these days that we can read about things happening all over the world while sitting in the comfort of our homes. In addition to the traditional ink and paper newspapers, there are also plenty of options available online.
Apart from the news, you should give special attention to the opinion pages. Read editorials, special articles, and columns on a regular basis, in order to study the opinions of others, and thus find new ideas you can write about.
Observe your society
Every good writer possesses extraordinary powers of observation, so put these to use in order to come across fresh ideas. Sitting at home all day, waiting for a new idea or a revolutionary thought to occur to you, is unlikely to be very effective. Instead, you should get out and about, and move around in your city and country, in order to observe all the happenings in your surroundings. By monitoring all the different behaviours you encounter at social or cultural events, you will surely find something to write about.
Join a literary club
Join a literary club in your town or city and attend meetings on a regular basis. You should communicate frequently with literary people, and actively participate in debates about current affairs and the problems of your society. These arguments and debates will leave you with many ideas which you might want to write about.
In order to gather ideas to write about, you should look into travelling frequently. Instead of confining yourself to your city or area, you should travel across the country, and to other countries as well, if your budget allows you to do so. Travelling is an amazing activity, which widens the mental horizons of an individual. By witnessing different cultures and places, you will definitely come across many things you can write about. If nothing comes to mind, you can still write a travelogue, which will undoubtedly be highly appreciated by readers if it is well-written and insightful.
