That depends, what do you want to achieve with mnemonics? If it’s just testing the waters to see what you can do/training your brain then how about you build upon your technique for memorizing words and try to remember famous quotes, poems or foreign language vocabulary with it? You don’t need any complex systems for those, and they can be highly rewarding. Maybe you could get yourself one of those ‘1000 quotes’ books or ‘Quote per day’ calendars and memorize one each morning.
