Here's my five point method for working out the chords to any song;
Work out the bass note (aka root note) of the first chord. i usually do this by finding all the notes on string 6 of the guitar
Repeat this for every chord until the sequence repeats
Go back to the first chord and work out if it is major or minor. Pausing or slowing down the song often will help lots!
Repeat this for every chord until the sequence repeats
You now have your verse or intro chords. Repeat this for every section of the song

General tips
Choose a song that repeats often. The more sections, or the less repetition, the harder everything becomes
Choose a song within your ability. If you can't imagine playing something like it, you probably won't be able to work it out by ear
Use headphones when listening to the song, you’ll hear the bass better and notes clearer
Strum the rhythm of a song with muted strings first
Be able to hear the difference between major and minor
