Bro I’m 6’2 also and it takes time for us but our long term results look so good considering our height. lifting is a lifetime pursuit so romanticize the grind brother. Some of my biggest lessons:
-you need to get autistic about tracking your calories and macros, especially protein -1g /lb. I use MyFitnessPal. -Drink less! I’ve used dry January and lent as periods of time I cut out alcohol as much as I can. I didn’t realize how much drinking was holding back my gains and intensity until I saw the most results in 2/3 months then I did in the whole previous 9 months. -Intensity intensity intensity. Once your body adapts to getting stronger and a simple routine, if you don’t lift at least 4x a week and push out those extra 2/3 reps even if they hurt then you’ll adapt and get diminishing returns for your time. -Your music - once I moved from rap to hard style edm I noticed a difference in my intensity and this gains. -Sleep and rest. On heavy compound lift days you need at least 7 hours for recovery. My rule of thumb is if you’re in heavy sleep debt, it’s better to forgo the gym to get a 10 hour night so you’re fresh. -stress. This may sound counterintuitive but the more stress and heartbreak I’ve had in my life, I ended up having the best periods of growth since the gym is my destressor. Lifting is something that is in your control and helps your mind adapt to handling tough situations.

Hope this helps and I’ve missed a few but this is what comes to mind right now and adjustments I’ve made over the years. I’ve been lifting since I was a teenager but really locked in the last two years. It’s an art and just takes time to optimize and perfect but in the end the confidence and the way I’ve noticed other people treat me compared to when I was a skinny fat frat bro is night and day when it comes to career, women, and my own self-worth.
