The biggest lessons I've learned about investing have come from the biggest mistakes I've made. I bought a pre-construction condo unit in a popular Toronto neighbourhood. I forked over a 20 per cent deposit to make the purchase. That was four years ago, the property still hasn't been built so I can't sell it or rent it out.
Investing should always be highly rational; humans on the other hand rarely are. Emotion creeps in, leading us to make choices that are often misaligned with our overall financial needs and goals. It's forgivable to make an occasional mistake every now and then, but striving to avoid the seven deadly sins of investing can help you dodge costly bundlers and help put you on a sound financial footing.
