How to manage adequate protein intake?

I'm a software engineer in my late 20s. I've been actively going to the gym for the past 6 months, with my aim being to bulk up. When I started, I chose to not opt for any diet supplements, since I still had much to improve in my natural diet and was willing to be patient for results to be seen; and I did see some mild results. Lately though, the realisation that my age is closer to 30 than to 20, is making me want to accelerate my fitness journey to some extent. I am convinced that my protein intake from natural diet doesn't work up to the required numbers and I've been actively considering the usage of protein supplement. I wanted to know how difficult it tends to be to manage your protein intake without a supplement (since that's what I was hoping to do for as long as I could)? And will adding a protein supplement make my fitness journey any easier?
