I've already learned a thing or two from mistakes I made. I kind of was forced into investment property when I had to move and couldn't sell my home. I ended up renting it out and made a bunch of mistakes.
taking action and actually making mistakes can also increase your learning quickly. You learn from mistakes very quickly! Well that's my experience. I hate making mistakes and losing money. So I ensure that I quickly make up that money the next time round, and I get smarter about my decisions. but taking action is a very good way to learn. You can get very paralysed by analysing too much and wanting to be too perfect
