How much money do you invest each month? And where do you put it? And how do you get that money?

Hello guys, <br><br>I'm 30 years old and currently I have 30 k cash on hand. I can't seem to find any good options where to put this money, so I need your advice. I wanna invest this money and get about 6-7 % profit each year. What is the best way? <br><br>And second question is, how much money you invest in a month? I have no money for this, since I'm on a tight budget. The biggest problem is that I'm currently in dark place mentally.<br><br>The income I have is about 1300 usd per month. I spend about 1000 usd and 300 goes to credit card. What is the best way to cut expenses and grow my profit to 1000 usd per month?<br><br>I live in an apartment and pay about 400 usd per month for that. What is best way to cut this? Maybe sleep on the floor? Not buying new clothes and not going out at all. What is the best way to reach these numbers?<br><br>Thank you very much.
