I'd agree. First, find the five major chords in one key, and learn them cold. Pick a key. I start my students in the key of G: G, C, D, Em, Am. With those 5, you have the key of g down. Without going into theory, a song will mostly be in a single KEY, a set of notes in sequence. the chords that start on each of those steps of that key are the major accompaniment you'll use. The main chords in a major key are the chords based on steps 1, 4, and 5, with the 2 and 6 also used. So, in our example, in the key of G, the notes are G, A, B, C, D, E, F#, and back to G. So the #1 is G, #2 is A, etc. So if you know G, C, and D (#1, #4, #5) you can play a lot of songs. And the Am (#2) and #6 (Em), and you've got most of what you need to get started.
Be able to finger them, and CHANGE the chords in tempo. Don't forget your right hand, and practice strumming as well as picking each string one at a time, up and down. When you can do THAT. You can play simple versions of many modern songs with these chords. So you'll feel accomplishment, and get a bit of variety. Also, then adding more chords will be easier, and so try another key.
Here are most of the primary chords you'll ever need, in several good "guitar" keys:
G: G, C, D are the main chords, then minors Em and Am
C: C, F, G are the main chords, then the minors Dm and Am (only 3 new chords, since you'll already know C, G, and Am from your work above in G)
D: D, G, A are the main chords, then the minors Em and Bm (only 2 new chords, A and Bm)
A: A, D, E are the main chords, then minors Bm and F#m (2 new chords, E and F#m).
So, again, start in the key of G, and work that up. Then add a few new chords over time. By the time you have these 12 chords, you'll be able to play nearly anything you want. Strum, sing, and have fun!!
