There are differences between traders and investors. But, you could always have it together at the same time, how? Well, if you want to buy something and 15 minutes after you buy, that thing goes up in price then you could sell and make a profit.
But, if you are buying something and then it goes down, then you could hold it for a year and then sell it for a profit. You are the same person, and you bought the same thing, but depending on what the outcome is, you turn out to be a trader or an investor. This is why it is not really that much of a big difference between the two, the difference is what happens meanwhile. If you are willing to do it, then it's fine.
Yeah, in my opinion it's not easy to have a passive mindset though. We are human beings and we have emotions and it's hard to keep them under control. I never became a great trader because I fail to keep my emotions in check to be fair, doesn't need to be just bad stuff, even on good feelings I overreact and that's always a trouble for me, like keeping something longer than I should because I like it type of good intentions did hurt me.
So, I would suggest that being a long term investor is easier. All you have to do is buy and hold, that will result with you making a good profit and that way you could always end up with a happy ending to your investment if you wait for it long enough.
