Real estate

I'm doubting becoming a real estate agent. I know how much hard work it takes and I'm doubting it. I know anything takes hard work but I'm so nervous that I'm making a mistake. But I want to invest in property and I know that being an agent will give me the experience I need for that while giving me a decent paycheck (if I work hard enough). But it's not my end goal. I'm passionate about working with animals but that's my end goal. First, I want to get some investment properties so I can do what I love. Like taking steps. Because I want to work nonprofit and that requires time and money. And I have to pay bills in the meantime. I don't know. I just feel like I'm going to fail.
