However, in the long run, having multiple investments won’t make you real rich if you aren’t capable of managing them well. It’s easy to invest one at a time, start with a small amount and challenge yourself to make it grow and progress through your knowledge, skills and perseverance on your investment.
Having multiple investments would be ideal as long as you pick them carefully. You wouldn't want to invest in many assets for all of those to end up being invaluable or a failure. You can pick only a few ones as long as they are incredibly good and profitable.
