hey there, welcome. don't despair on those chords. i remember wen i began learning guitar. i thought these chords were impossible to play on the nylon string acoustic i was learning on. so i quit 4 2 years. BIGGEST MISTAKE OF MY LIFE SO FAR!!! seriously, don't give up. regular practice will make perfect. jus keep playing the 'D' chord at a steady, n slow count of 4. then switch to the 'A' chord then back to the 'D' all in the same timing. this will build up your finger strength. jus keep adding and alternating these chords and keep adding more. but do not give up unless u really want 2
