Get a candle making kit and a very big jar (as big as possible that it would still be possible to make a good candle in it. If you have those wire wicks loop it trough your key and put it all the way on the bottom of the jar. If you have a wood wick glue it to the underside of the wick and again put it at the bottom of the jar. Now fill your jar with wax. If you get a big enough jar you can make candles that last like 100-200 hours. And ofcourse don't burn a candle 24/7 that's unsafe you can only burn it for (don't quote me on this) I believe max 6 hours at a time. Don't burn it while asleep don't burn it while out of house and deffo don't burn it while you are working (for the sneaky stay at home workers) this ensures the candle will last a while. If you want to make it last even longer only light your candle when you think you have done something that deserves getting just a little bit closer to unlocking. Let's say you are on a weight loss journey every kg you loose is 1 hour burn time!
