If you're very self motivated person, then you can succeed as an insurance/unit trust/real estate/MLM sales person.

l these jobs don't have basic salary and you need to be very persistent in doing your work everyday even though a lot of people will reject you. If you're easily depressed or easily discouraged, don't even try it because it can be very demotivating to face rejections daily.

Being hardworking alone won't take you far in this career. You need to know what's your motivation to do it and be strong. Remember also that when people rejected your sales pitch, don't take it personally. Sometimes it is only because they are not ready /scared to commit to another long-term payment. (esply insurance)
