That is why people should be risk taker because if you will become risk taker you are taking steps close to success because the only risk that you can have is not the taking the risk so if you don't take risk, you are risking yourself to just stick with average life with no changes. It seems confusing but the point is, be a risk taker and don't be afraid to get losses because it will strengthen you.
As long as people taking risk that have some possibility to be success then it's worth to give a try. For those things who have an obvious risk and no way we can get profit from in the long run, we must avoid it.We don't want in the first place to just take some risk without anything good in return because we want that our risk and effort pays off someday.
Investors who put money to an investment knowing that they might lose is not just a risk taker but they believe that by taking the risk they will be succeed and soon will overcome those.
