Ok so Im thinking about joining a little band when Im older nothing big but my problem Is going from chord to chord I cannot remember the frets...

What I mean is If I cant move from chords after chords I just screw up Like going from D7 to A minor I just cant progress from chord to chord help!
I know everybody says this....but it just comes naturally after you practice.
If you like Blues/Rock then add me as a friend. I need to talk to some Blues/Rock Musicians and need reccomendations.
