Here’s my quick advice. Recognize up front how hard the guitar is to play. It takes a lot of time, effort and patience. It will give you realistic expectations. People that you see on TV and the like have spent 1000s of hours practicing. Lastly, find a teacher. If nothing else, it gives you someone to answer to. No one wants to show up for a lesson with only 20 minutes of practice for the entire week.

If it was easy, everyone would do it. That’s what I tell myself over and over when I don’t feel like practicing. You just need to decide it’s something you are going to do and never look back.

I agree. I think a good rule of thumb is for your own enjoyment one hour a day. If you want, to be a real musician - three hours a day.

An hour plus really isn’t hard to do if you just make your life more efficient. I do an hour first thing in the morning instead of staring at my phone or watching tv. After that, I get another hour or so in in 20 minute increments and that is literally every day with very few exceptions. And I have kids and work more than a full time job. Anyway, it’s just a matter of how bad you want it, much like anything else worth doing.

If you want to play Johnny B Goode, then do it. Just make sure to start very slow until you get the fingering down. Remember, if you practice sloppy, you will play sloppy.
