I feel like I'm spending too much. Please tell me how I should manage my money?

I just want to say thanks to everyone who replied. I am in a pretty similar situation and these tips are definitely going to be helping me out too. Just transferred 500$ to savings, and definitely growing with my next deposit.
I'm the same way, impulse buying. I need to block Amazon. So much money wasted.

Thanks Joyce for making this thread and everyone else for their thoughtful replies. Really changed my way of thinking regarding money.
